Why Do Vasodilators Cause Tachycardia And Palpitation
Vasodilators: Vasodilators do what the name implies: these compounds dilate blood vessels, resulting in a decrease in blood pressure. As the baroreceptors detect this, they command the autonomic nervous system to increase adrenaline output. This, in turn, increases heart rate and increases cardiac irritability. ...Read moreSee 1 more doctor answer
Palpitations are an awareness of extra heartbeats which most of us have. The sensation can be single or multiple and can sometimes last minutes. Different people may feel other symptoms along with them such as dizzy, lightheaded or short of breath. The palpitations are almost always atrial or ventricular premature beats. Usually benign but they are also ...Read more

Dysautonomia: Dysautonomia refers to an abnormality of function of the autonomic nervous system. There are two divisions of the autonomic nervous system: the sympathetic and the parasympathetic. Although the latter occasionally may be involved, abnormal function of the sympathetic division produces the most striking symptoms of dysautonomic syndromes. The term orthostatic hypotension is often used as a synonym. ...Read more
Palpitations: Salt per se shouldn't precipitate palpitations although it can raise the blood pressure. To affect heart action it would have to cause fluid retention which could put strain on a weak heart but not one with healthy heart and kidneys. Caffeine, nicotine and alcohol can induce palpitations, however. ...Read more
Tough to say...: There are certain rhythm problems that only come on with exertion. Palpitations however, are an unnatural awareness of your heartbeat, so even being severely deconditioned can do it. I'd find a cardiologist or cardiac electrophysiologist and have them run you on a treadmill while wearing ekg. If that doesn't work, we'd get you an "event monitor" to record the palpitations. ...Read moreSee 1 more doctor answer
Come and go: Everyone has palpitations sometimes-they're not necessarily abnormal. Some factors that may contribute: caffeine, nicotine, alcohol, lack of sleep, stress. Certain meds(even over the counter) & electrolyte imbalance (as from diarrhea, vomiting, excessive sweating, and dieting). Lying quietly, especially face down or left side down will cause you to feel them more. If still troublesome, seek help. ...Read more
What would cause fast heart rate and pvcs while drinking? Ii have a history of pvcs and sinus tachycardia.
Atrial Fibrillation: Atrial fibrillation is disorganized heart muscle activity (looks like quivering) of the upper chambers of the heart. The result is that the bottom chamber doesn't get it's usual rhythmic electrical stimulus and it squeezes after slowly filling for longer than it usually takes. This feels like fluttering with strong beats in between. You need medical attention -- can be dangerous. ...Read moreSee 1 more doctor answer
I noticed short(1s) heart rate squizzes (not palpitations) followed by face flushing, hot feelings and sweatings. What can cause this?
Vagal Response: In general, most cardiac rhythm disturbances will not cause nausea. However, there is a condition that can cause both nausea and arrhythmia (particularly slow heart rate), and that is called a vagal response. This is an abnormal reflex response which causes the heart rate to abnormally slow, and also has concurrent symptoms of nausea and/or "cold sweats" and/or lightheadedness. ...Read more
Exercise causes to me chest pressure, palpitations and indigestion but if I stop most symptoms are relieved but why palpitations last for hours?
Why shortness of breath happens during GERD attack & why do you feel spasms that mimic heart palpitations?
Heart as an organ: The heart is a sensitive organ and as such likes a certain mileu. Acid reflux (heart burn) is not a comfortable condition with acid in an otherwise alkaline mileu (esophagus), hence can cause GI pain and/or masquerade as chest pain. This perturbs the heart and has been associated with atrial fibrillation and/or simple extra beats. This is the explanation that is believed presently. ...Read moreSee 1 more doctor answer
Blood vessels have the capability of increasing or decreasing their diameter. When a blood vessel dilates, it generally leads to lowered blood pressure. Drugs that cause this are termed vasodilators. These can act on arteries or veins. Some classes of vasodilators include nitrates, calcium channel ...Read more
