Biology

Ratling [72]2 years ago
7 0

The P wave of the electrocardiogram is considered as a signal from the DEPOLARIZATION of the atria in the heart. This depolarization drives the contraction of the atrial musculature.

An electrocardiogram (ECG) is a device that records the electrical activity of the heart. This record can then be used to diagnose different heart conditions.

The P waves occur when the sinoatrial node generates an action potential which is capable of depolarizing the atria.

This depolarization is then followed by atrial contraction and an increase of the pressure in the atria.

When the body senses a state of hypoperfusion, the sympathetic nervous system releases epinephrine, the effects of which?
lutik1710 [3]
Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate. Such factors as stress, caffeine, and excitement may temporarily accelerate your heart rate, while meditating or taking slow, deep breaths may help to slow your heart rate.
