What is the fast and weak heartbeat?

The heart beats fast and weakly due to hyperthyroidism, arrhythmia, heart failure and other reasons.

1. Hyperthyroidism

patients due to excessive thyroid hormones in the body, acting on the heart, accelerate the heart rate and enhance the contractility of the myocardium, resulting in fast and weak heart beat.

2. Arrhythmia

arrhythmia patients due to abnormal electrical signals, resulting in faster heart beat, but due to uncoordinated myocardial contraction, the heart pump weak, so that the heart beat weak.

3. Heart failure

patients need to make the heart beat faster to compensate for the lack of blood pump, but due to the heart itself damaged, resulting in weak heart beat intensity.
