Question

what type of crystals use in vasodialation during ECG?​

Answer 1

Answer:

.

Explanation:

10 electrodes attached to the body are used to form 12 ECG leads

Answer 2

Explanation:

Electrocardiography is the process of producing an electrocardiogram (ECG or EKG[a]), a recording – a graph of voltage versus time – of the electrical activity of the heart using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle (heartbeat). Changes in the normal ECG pattern occur in numerous cardiac abnormalities, including cardiac rhythm disturbances (such as atrial fibrillation and ventricular tachycardia), inadequate coronary artery blood flow (such as myocardial ischemia and myocardial infarction), and electrolyte disturbances (such as hypokalemia and hyperkalemia).
