早博是冠心病最常见的心律失常类型。冠心病伴发早搏多为病理性早搏,当心电图检查呈现室性二联律、三联律、多源性早搏或多发性早搏时必须提高警惕,因为这些改变都是严重或致命性的心律失常,可以成为室性心动过速、心室颤动及猝死的重要危险因素。所以,老年冠心病人应定期进行心电图检查,至少半年检查1次。一旦发现有室性早搏, Early Bo is the most common form of arrhythmia of coronary heart disease. Coronary heart disease with premature beats is mostly pathological premature beats, when electrocardiogram showed ventricular bigeminy, triple therapy, multi-source premature beats or multiple premature beats must be vigilant, because these changes are serious or fatal arrhythmias, Can become an important risk factor of ventricular tachycardia, ventricular fibrillation and sudden death. Therefore, elderly patients with coronary heart disease should be regular ECG, at least six months to check 1. Once found premature ventricular contractions,
