Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).
High heart rates with associated symptoms such as chest tightness, palpitations or heart pounding/racing, fainting, dizziness, lightheadedness, shortness of breath, or fatigue, it may suggest an ...
The harder your heart has to work to pump blood throughout your body while you’re not exerting yourself, the higher your resting heart rate. That’s why a lower resting heart rate is indicative ...
Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans). [1] The normal resting heart rate is 60–90 bpm in an average adult. [2]

A medical monitoring device displaying a normal human heart rate. Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.
The electrical impulse is generated at a different focus within the atria of the heart each time. WAP is positive once the heart generates at least three different P-wave formations from the same ECG lead. Then, if the heart rate exceeds 100 beats per minute, the phenomenon is called multifocal atrial tachycardia. [citation needed]
Heart rate is the rate or speed at which your heart beats, and it’s determined by counting the number of beats per minute while you’re at rest. In all adults, including seniors, a normal ...
