Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure.
It consists of a brief speed-up in heart rate, followed by a slow decrease back to the baseline rate. PVCs can occur naturally in most otherwise-healthy adults, so measuring the characteristics of a given person's HRT can offer a non-invasive way to evaluate certain aspects of their cardiac or autonomic function without applying artificial ...
Rapid heart rates may produce significant symptoms in patients with pre-existing heart disease and can lead to inadequate blood flow to the heart muscle and even a heart attack. [ 1 ] In rare situations, atrial flutter associated with a fast heart rate persists for an extended period of time without being corrected to a normal heart rhythm and ...
The impulse then spreads through both ventricles via the bundle of His and the Purkinje fibers causing a synchronized contraction of the heart muscle and, thus, the pulse. [citation needed] In adults, the normal resting heart rate ranges from 60 to 90 beats per minute. The resting heart rate in children is much faster.
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).
Future care could use heart data from mobile devices to ensure timely access to medical care. Additionally, monitoring heart conditions could help assess how well treatments work. [15] Many people worry when they feel palpitations. [1] However, in most cases, the cause of palpitations is harmless, so detailed medical tests are often not needed. [1]
