Heart blockage may be due to arrhythmia, which causes irregular electrical activity of the heart, irregular heart contraction, and the heart beating randomly, so it feels blocked. This is a very common cardiovascular event that may occur many times in a person’s life, so don’t panic and feel your pulse with your hand. If the pulse is irregular, the panic may be caused by arrhythmia, so it is best to go to the hospital for an electrocardiogram in time. If the heart does not panic to the hospital is very necessary to do dynamic ECG, that is, 24-hour ECG monitoring, back on the body can go home, you can walk freely, when the time to take off the instrument can analyze the 24-hour ECG activity, to see if there are arrhythmias, that is, the cause of the heart blocked panic. If there is a black eye and unsteady standing, you need to go to the hospital emergency department as soon as possible.
