What is BP
Blood pressure (BP) tells us measure of the force exerted by the blood against the walls of the arteries as the heart pumps it around the body. It is essential to check your BP because it indicates how effectively the heart is pumping blood and how well the arteries are carrying that blood to various parts of the body.
Blood pressure is typically expressed as two numbers:
- Systolic Pressure: This is the higher of the two numbers and represents the pressure in the arteries when the heart contracts or beats. It is the moment when blood is forcefully pushed out of the heart into the circulatory system.
- Diastolic Pressure: This is the lower number and represents the pressure in the arteries when the heart is at rest between beats. It reflects the minimum pressure in the arteries when the heart is not actively pumping.
Blood pressure is measured in millimetres of mercury (mmHg). A standard blood pressure reading is written as systolic over diastolic, such as 120/80 mmHg.
Here’s what these numbers mean:
- Normal Blood Pressure: A normal blood pressure reading is typically around 120/80 mmHg. This indicates that the pressure in the arteries is within the healthy range.
- Hypertension (High Blood Pressure): Hypertension is diagnosed when blood pressure consistently exceeds 130/80 mmHg. It’s a significant risk factor for heart disease, stroke, and other health issues.
- Hypotension (Low Blood Pressure): Hypotension occurs when blood pressure is lower than 90/60 mmHg. Low blood pressure can cause symptoms like dizziness, fainting, and fatigue.
Blood pressure is a dynamic parameter that can change throughout the day in response to various factors such as physical activity, stress, diet, and emotions. It’s important to have regular blood pressure check-ups to monitor your cardiovascular health and detect any abnormalities early.
Maintaining a healthy blood pressure range is crucial for overall well-being because high blood pressure can strain the heart and arteries over time, increasing the risk of cardiovascular diseases, while low blood pressure may lead to inadequate blood flow to vital organs. Lifestyle modifications, such as a balanced diet, regular exercise, stress management, and, in some cases, medication, can help manage blood pressure and reduce the risk of associated health problems.
How narrow arteries can cause BP fluctuation?
Narrow arteries can indeed contribute to fluctuations in blood pressure, particularly higher blood pressure (hypertension). This is primarily because the narrowing of arteries, a condition known as atherosclerosis, increases resistance to blood flow, making it more challenging for the heart to pump blood effectively. Here’s how narrow arteries can lead to blood pressure fluctuations:
Increased Resistance: When arteries narrow due to the buildup of fatty deposits (plaques) along their inner walls, the space through which blood can flow becomes restricted. This increased resistance means that the heart has to pump harder to push blood through these narrowed arteries.
Increased Pressure: To overcome the resistance and maintain an adequate flow of blood to various parts of the body, the heart pumps with greater force. This increased force results in higher systolic blood pressure, which is the pressure during the heart’s contraction (the top number in a blood pressure reading).
Fluctuations in Blood Flow: Narrowed arteries may not always allow for consistent blood flow. Blood flow can become turbulent, leading to variations in pressure within the arteries. This turbulence can cause fluctuations in systolic and diastolic blood pressure.
Risk of Hypertension: Over time, chronic narrowing of arteries due to atherosclerosis can contribute to the development of hypertension (high blood pressure). Hypertension is often referred to as the “silent killer” because it may not have noticeable symptoms but can damage blood vessels, the heart, and other organs.
Blood Pressure Variability: The fluctuations in blood flow caused by narrowed arteries can lead to variations in blood pressure readings, both systolic and diastolic. Blood pressure may spike when the heart is pumping against the resistance created by narrowed arteries and may drop when the heart is at rest.
Increased Cardiovascular Risk: Hypertension resulting from narrowed arteries is a significant risk factor for heart disease, stroke, and other cardiovascular complications. These conditions can further affect blood pressure regulation.
It’s important to note that atherosclerosis and arterial narrowing are often the result of long-term factors, including an unhealthy diet, lack of physical activity, smoking, and genetics. Managing these risk factors and seeking medical attention when necessary is crucial for preventing or managing arterial narrowing and the associated blood pressure fluctuations. Lifestyle modifications, such as a heart-healthy diet, regular exercise, and medications prescribed by a healthcare provider, may be recommended to address these issues and help maintain healthy blood pressure levels.
Angiography and Angioplasty
Let’s discuss angiography and angioplasty in a conversational tone:
Angiography:Angiography is a medical procedure used to visualize the blood vessels in various parts of the body, typically the heart and blood vessels surrounding it. It’s done to diagnose and assess conditions like coronary artery disease (CAD), peripheral artery disease (PAD), and aneurysms.
Here’s how it works: A contrast dye is injected into the bloodstream, usually through a catheter inserted into a blood vessel, often in the groin area. X-ray imaging is then used to capture real-time images of the blood vessels, allowing doctors to identify blockages, narrowings, or other abnormalities.

Angioplasty: Angioplasty, on the other hand, is a medical procedure often performed immediately after an angiography when a blockage or narrowing is detected. It’s also known as percutaneous transluminal coronary angioplasty (PTCA) or balloon angioplasty when used in the coronary arteries.
In angioplasty, a small balloon-tipped catheter is guided to the site of the blockage through the same catheter used for angiography. Once in position, the balloon is inflated. The pressure from the inflated balloon compresses the plaque or blockage against the artery walls, widening the artery and restoring blood flow. This can alleviate symptoms of conditions like angina (chest pain) and reduce the risk of heart attacks.
In some cases, a stent (a tiny mesh-like tube) may be inserted at the site of the blockage to help keep the artery open. This is called a stent placement or stent implantation.

Both angiography and angioplasty are valuable procedures for diagnosing and treating conditions affecting the blood vessels, particularly in the heart and surrounding areas. They are often performed by cardiologists and interventional radiologists and can be life-saving in cases of severe blockages or critical arterial conditions.
BPM and sinus rhythm (Can Apple Watch Check BPM & ECG?)
BPM and sinus rhythm are terms related to the electrocardiogram (ECG or EKG) measurements, which are used to assess the electrical activity of the heart. They are part of the data that can be checked on an Apple Watch, but the capabilities of a consumer device like the Apple Watch differ from a hospital-grade ECG machine.
Here’s what BPM and sinus rhythm mean in the context of ECG:
- BPM (Beats Per Minute): BPM refers to the heart rate, which is the number of heartbeats (or electrical impulses) that occur in one minute. It’s usually measured in beats per minute. A normal resting heart rate for adults typically ranges from 60 to 100 BPM, but it can vary depending on factors like age, fitness level, and health condition.
- Sinus Rhythm: Sinus rhythm refers to the normal electrical pattern of the heart, where electrical impulses originate from the sinus node (the heart’s natural pacemaker). It’s characterized by a regular, organized pattern of heartbeats. A sinus rhythm is considered normal and healthy. Deviations from a sinus rhythm can indicate various cardiac conditions.
Now, regarding the Apple Watch:
- The Apple Watch has an ECG feature that allows users to record an ECG using the watch’s built-in sensors. This feature provides a graphical representation of the heart’s electrical activity, which can help detect irregularities in heart rhythm, such as atrial fibrillation (AFib).
- However, it’s important to note that the ECG feature on the Apple Watch is designed for consumer use and may not be as precise or comprehensive as a hospital-grade ECG machine. It provides valuable information for personal health monitoring and early detection of certain irregularities, but it’s not a replacement for a thorough clinical ECG performed by healthcare professionals in a hospital setting.
- The Apple Watch can check your heart rate (BPM) continuously throughout the day and alert you to any significant changes. It can also detect irregular heart rhythms and notify you to seek medical attention if necessary.
Why BP Fluctuate?
Blood pressure (BP) can fluctuate and become either high (hypertension) or low (hypotension) due to various factors and underlying causes. Here are some common reasons for fluctuations in blood pressure:
1. Lifestyle Factors:
- Diet: Consuming high-sodium diets can lead to temporary spikes in blood pressure. A diet rich in fruits, vegetables, and whole grains can help maintain healthy blood pressure.
- Physical Activity: Lack of physical activity can contribute to high blood pressure. Regular exercise can help lower it.
- Stress: Stress and anxiety can lead to temporary increases in blood pressure. Chronic stress may contribute to long-term hypertension.
2. Medical Conditions:
- Hypertension: Persistent high blood pressure can be caused by underlying conditions, such as kidney disease, hormonal disorders, or narrowing of the arteries (explained later in this article).
- Hypotension: Low blood pressure may result from conditions like dehydration, heart problems, anemia, or endocrine disorders.
3. Medications:
- Some medications can affect blood pressure. For instance, certain antihypertensive drugs lower blood pressure, while others, like decongestants or nonsteroidal anti-inflammatory drugs (NSAIDs), can raise it.
4. Age and Genetics:
- As people age, their risk of developing hypertension increases. Genetic factors can also play a role in predisposing individuals to high or low blood pressure.
5. Diet and Nutrition:
- A diet high in salt (sodium) can lead to high blood pressure. Conversely, not getting enough potassium, calcium, and magnesium in your diet can also impact blood pressure regulation.
6. Hormonal Changes:
- Hormonal fluctuations, such as those occurring during pregnancy or menopause, can affect blood pressure.
7. Smoking and Alcohol:
- Smoking tobacco and excessive alcohol consumption can contribute to high blood pressure.
8. Obesity:
- Being overweight or obese is a significant risk factor for hypertension.
9. Sleep Apnea:
- Sleep apnea, a condition characterized by interrupted breathing during sleep, is associated with high blood pressure.
10. Chronic Conditions: – Chronic conditions like diabetes and kidney disease can lead to long-term hypertension.
11. Medication Adherence: – Not taking prescribed medications as directed can lead to uncontrolled blood pressure.
It’s essential to note that blood pressure can naturally fluctuate throughout the day, depending on activities, stress levels, and other factors. However, persistent or extreme fluctuations, especially if they are accompanied by symptoms like dizziness, chest pain, or shortness of breath, should be evaluated by a healthcare professional.
Managing blood pressure often involves lifestyle changes, such as dietary modifications, regular exercise, stress reduction, and medication if necessary. Regular monitoring and medical check-ups are crucial to maintaining healthy blood pressure levels and reducing the risk of related health problems.
