Arrhythmias in the elderly are divided into the following types: fast arrhythmias, slow arrhythmias, and irregular arrhythmias. There are various manifestations, some patients show a confused heartbeat, others have chest tightness, palpitations, sweating and weakness, while the best identification is done by a doctor. The first step is to feel one’s pulse, whether it is beating faster, more than 100 beats per minute, or beating irregularly or slowly, which is the most important way of identification. Therefore, patients with dizziness, chest tightness, palpitations symptom performance is not specific, you can not assume that because of dizziness, chest tightness, palpitations, it must be arrhythmia, in fact, you also need to combine their own pulse, heart rate, and even to the hospital for electrocardiogram examination. One of the worst manifestations of arrhythmia in patients is syncope and loss of consciousness, which usually indicates that the malignant arrhythmia has affected heart pumping and organ perfusion. Once the symptoms of transient syncope, loss of consciousness, or even convulsions occur, then the patient should go to the hospital for resuscitative treatment as soon as possible.
