1 Heartbeat suddenly increases, alert for atrial fibrillation
Actually, a sudden increase in the heartbeat is not necessarily a heart problem, it may be caused by physiological reasons – when we perform physical labor, strenuous exercise, or experience emotional changes such as fright, nervousness, fear, anger, etc. , the heartbeat will speed up. But as long as the heartbeat fluctuates within the normal range (60-100 beats/min), it is a healthy heartbeat.
It should be noted that if the heart beats too fast (more than 100 beats/min) for a long time, or even 300-500 beats/min when excited, you should be alert to atrial fibrillation.
Atrial fibrillation is the most dangerous type of arrhythmia. To a certain extent, it means that atrial blood cannot be effectively discharged, and blood retention is easy to form thrombus; and the continuous contraction and relaxation of the heart, the thrombus is easy to fall off, which may increase cerebral infarction, arterial Risk of diseases such as embolism!
2 The heart skips a beat, possibly a premature beat
When many people stay up late to work overtime and are overworked, their hearts may “gump” a bit, feeling like they missed a beat. This is most likely a premature beat, a change in the heart’s rhythm, which contracts a little earlier. Premature cardiac beats can occur in any population and are generally classified into the following two situations:
①Atrial premature beat: Generally, there is no danger and no special treatment is required. However, if there are too many premature atrial contractions, it may affect the cardiac ejection function to varying degrees, and even cause atrial fibrillation, which can be treated with drugs.
②Premature ventricular contractions: If there is no structural heart disease and the number of premature ventricular contractions is not large, such as only a few hundred in 24 hours, no special treatment is required, and the main focus is to improve the lifestyle, such as not drinking strong tea, coffee, Do not stay up late, avoid emotional agitation, etc.
However, premature ventricular contractions in patients with critical structural heart disease such as myocardial infarction, cardiomyopathy, heart failure, and hypokalemia may cause ventricular fibrillation, which is immediately life-threatening. Therefore, active symptomatic treatment is required, and it is used when necessary. Antiarrhythmic drugs.
