Question

1. Why might prolonged tachycardia result in heart failure?.

Answer 1

Ans) Tachycardia-induced cardiomyopathy develops slowly and appears reversible by left ventricular ejection fraction improvement, but recurrent tachycardia causes rapid decline in left ventricular function and development of heart failure. Sudden death is possible.

- Tachycardia occurs when an abnormality in the heart produces rapid electrical signals that quicken the heart rate, which is normally about 60 to 100 beats a minute at rest. But if left untreated, tachycardia can disrupt normal heart function and lead to serious complications, including: Heart failure.
