A stroke occurs when the blood flow to part of the brain is blocked or reduced, depriving it of oxygen and nutrients. The damage caused by a stroke can range from mild to severe, and can have long-term effects on physical, mental, and emotional health.
When it comes to heart rate, any condition that increases the risk of stroke may be associated with an abnormal heart rate. Generally, a heart rate that is too fast (tachycardia) or too slow (bradycardia) can cause a stroke.
Tachycardia is when the heart rate is faster than normal, usually over 100 beats per minute. This can be caused by a variety of conditions, including coronary artery disease, thyroid disease, anemia, and some medications. Tachycardia can cause the heart to work too hard, leading to a stroke.
Bradycardia is when the heart rate is slower than normal, typically less than 60 beats per minute. This can be caused by a variety of conditions, including heart block, some medications, and heart failure. Bradycardia can cause the heart to not pump enough blood, leading to a stroke.
In addition to a fast or slow heart rate, a stroke can also be caused by an irregular heart rhythm (arrhythmia). This is when the heart beats in an abnormal pattern, which can cause a clot to form in the artery that supplies blood to the brain. This can lead to a stroke.
Most people do not experience any symptoms associated with a fast or slow heart rate or an irregular rhythm until it becomes a medical emergency. However, if any of the following signs and symptoms are experienced, seek medical help immediately: chest pain, shortness of breath, dizziness, fainting, confusion, or difficulty speaking.
In conclusion, a heart rate that is too fast or too slow, or an irregular rhythm can all lead to a stroke. If any of the signs and symptoms of these conditions are experienced, seek medical help immediately.
