What are the symptoms of premature heart attack?

Premature heart contractions generally refer to extrasystoles. Symptoms of extrasystoles include palpitations, chest pain, nausea, etc. Detailed analysis is as follows:

1.

During extrasystoles, patients may feel their heart beat faster or more strongly, resulting in palpitations, manifested as feeling the heart beating in the chest, or feeling that the heart missed a beat.

2.

Some patients with chest pain may feel chest tightness during extrasystoles. This discomfort may be similar to mild chest pain, and the duration is usually a few seconds to a few minutes.

3.

When patients with nausea extrasystoles are ill, they may feel nausea or stomach discomfort, usually related to cardiac stimulation nerves.
