Tachycardia usually requires monitoring of blood pressure and heart rate, administration of beta-blockers such as metoprolol and bisoprolol as necessary, and symptomatic treatment with proprietary Chinese medicines such as heart stabilizing granules, ginseng heart capsules or non-dihydropyridine calcium channel blockers such as diltiazem. Rapid heartbeat can be caused by a variety of reasons. For fever and tachycardia caused by infection and other factors, medication related to slowing down the heart rate needs to be given, and its basic treatment is the application of anti-infective drugs, while tachycardia in hemorrhage and shock state often requires treatment related to blood volume replenishment. For tachycardia due to hyperthyroidism, non-selective beta-blockers, such as propranolol, can be given for symptomatic management, in addition to antihyperthyroid related medications. For organic heart disease, basic treatment is often required for the primary cause.
