When you put your hand on your heart, you can’t feel the heartbeat. It may be caused by obesity, weakened heartbeat, etc. It is recommended to go to the hospital for examination. 1. Obesity: due to the fat produced by obesity thickening of the chest wall, the heartbeat can not be clearly conducted to the surface of the chest wall and can not feel the heartbeat. 2. Weak heartbeat: some diseases such as coronary heart disease, heart failure, etc., can cause myocardial ischemia leading to weak heartbeat. Pericarditis, pericardial effusion, cardiac tamponade and other diseases can increase the exudate and cause the heartbeat to weaken due to pressure on the heart. If you can’t feel the heartbeat by hand, you can use a stethoscope to listen to the heart, and the strongest point of the apical beat is generally located in the fifth intercostal space (i.e., the next intercostal space between the ribs where the nipple is located) on the medial side of the left midclavicular line of the heart, 0.5-1.0 cm. If there is any discomfort, it is recommended that you seek medical attention in a timely manner.
