Systolic tremor

The systolic tremor is a small tremor felt on the palm of the hand when palpating. It is similar to the respiratory tremor felt in the throat of a cat, also known as cat asthma. The mechanism of tremor is the same as that of the sarcoma. It is caused by the blood flowing through the narrow caliber or in an abnormal direction to form a vortex, which causes the valve, blood vessel wall or heart cavity wall vibration to be transmitted to the chest wall. After the tremor is found, the location and source (valve, large blood vessel, or septal defect) should be determined first, and then the phase (systole, diastole, or continuity) in the cardiac cycle is determined. Finally, its clinical significance is analyzed.
