Why Does My Heart Rate Drop When I Run
Dizzy Spell?: Orthostatic hypotension, also known as postural hypotension (dizzy spells) is a form of hypotension in which a person's blood pressure suddenly falls when standing up or stretching. The symptom is caused by blood pooling in the lower extremities upon a change in body position. It is quite common and can occur briefly in anyone. ...Read more
PVCs?: Some people experience palpitations or premature atrial or ventricular contractions with exercise; others have a more concerning condition: exercise-induced ventricular tachycardia. In either event, if this bothers you, i would definitely see a cardiologist and discuss monitoring and next steps. ...Read more
Parasympathetic : The hr is influence by sympathetic ( adrenergic) and parasympathetic forces. Adrenergic or sympathetic drive ( fight or flight ) leads to tachycardia and parasympathetic forces leads to bradycardia. When the body relax, there is withdrawal of sympathetic and increase of parasympathetic influence. ...Read more
Not sure: Perhaps you do not hyperventilate long enough or hard enough to make heart rate rise. Why do you hyperventilate in the first place would be my question to you? What causes you to do so? Is this an issue that can be addressed for you? I would not be so worried about your heart rate not rising and more interested in what causes you to hyperventilate and how to address that issue.

It doesn't: Heart rate and breathing must increase with exercise. You are describing an artifact of monitoring. Sometime when pulse is slow it gets counted twice. When it speeds up it gets counted once. With a machine it is often worse! so a pulse of 50 gets counted at 100 , rises to 80 with mild exercise and appears to have dropped. ...Read more
Can slow or increase: Standing up quickly causes blood to pool in the legs and causes the blood pressure to drop transiently. How transient depends on how compensated a person is. If dehydrated, elderly, anemic, or diabetic, then the blood pressure can remain depressed and will actually lead to a fast heart rate. The only time that the hr would slow would be if the vagus nerve got activated - vasovagal response. ...Read more
Here are some reason: During excercise the muscles increase demand for blood and therefore the arterial system is dilated for increased blood flow. Additionally excercise in general increases the compliance of the vessels and as a result diastolic blood pressure is decreased. ...Read moreSee 1 more doctor answer
Arrhythmia: Normally, your heart rate should slow down, when relaxing. Anything over 100 bpm, after a couple minutes of rest, is unusual. You may have an electrical short circuit in your heart, that causes it to go faster. There can also be another condition making it increase from outside the heart itself. See your doctor for a thorough history and physical and referral to a heart rhythm specialist. ...Read more
I have random heart palpitations. When I check my pulse when that happens, the heart rate is not particularly fast. Is that normal? I do feel pinching

Heart fast supine: Need to know what you mean by fast? It may beat faster for a short time because when you assume the supine position the fluid collected in your lower extremities reenters your blood stream your heart must beat faster to move it around until you pee out the difference or until your BP and heart rate control systems thinks things are OK ...Read more
