Bradycardia

Bradycardia is a pathological phenomenon of abnormally slowed pulsation caused by heart disease. The heart rate of normal adults is between 60-100 times per minute, and less than 60 times is called bradycardia. Bradycardia is an important type of arrhythmia. In some patients, the basal heart rate is usually slow, about 50-60 times per minute, or even less than 50 times. Usually, they have symptoms of dizziness, fatigue, burnout, and poor mentality. In some patients, the normal heart rate can be normal, bradycardia can suddenly appear, drop below 40 times per minute, dizziness, transient dark eyes, fatigue, palpitations, chest tightness, shortness of breath, sometimes a sense of shock in the precardiac area, serious Can occur syncope. There are also some patients with dizziness, fatigue, syncope, and a long-term cardiac arrest with intermittent heartbeat. It is worth noting that, because athletes usually train more often, their heart function is stronger, their heart rate may be lower than 60 beats per minute, and they are asymptomatic. This is a physiological phenomenon. Bradycardia
