Under normal circumstances, when the heart is beating, you can’t feel it. Premature beats are irregular heartbeats, which usually feel like a sudden “thump” of the heartbeat, but the sensation is not consistent from person to person, and some people feel that their heart wants to jump out of their throat. Some people may also feel a pause in their heartbeat after the “thump”. Although the heartbeat caused by premature beats may feel an obvious “thump” once or several times, the pulse caused by premature beats may be weaker, so it may not be clear when feeling the pulse, and the pulse may suddenly feel slower once or several times or there may be intermittent pulses, which is also called “missed pulse” phenomenon. This is also called “missed pulse”. Occasional premature beats are often not easy to notice; if they occur frequently, you may feel panicky, or more seriously, you may feel dizzy and have tightness in your chest, and then you need to seek medical attention. Premature beats are usually most obvious at night before going to bed, because the environment is quiet and relaxed, so it is easy to notice the palpitations and other symptoms, and ignore them during the day.
