When heart attack causes generalized trembling, it is necessary to find out the cause, if it is arrhythmia, it is necessary to defibrillate, if it is low blood pressure, it is necessary to take antihypertensive drugs, such as dobutamine, etc. as prescribed by the doctor. 1. Cardiac arrhythmia: convulsions due to cardiac arrhythmia may occur in serious cases such as ventricular fibrillation and ventricular flutter, which require immediate electrical defibrillation to restore the sinus heart rate. 2. Hypotension: Convulsions may occur when blood pressure drops significantly, and severe cases may even lead to hypotensive shock, requiring the use of drugs such as dobutamine to elevate blood pressure by intravenous drip. 3. Heart failure: convulsions occur when heart failure occurs, at this time you need to use diuretic drugs, such as furosemide, etc., vasodilator drugs, such as nitroglycerin, etc., in order to reduce the burden on the heart. Myocardial infarction causes generalized trembling, it is recommended to consult the cardiology department of regular hospitals for active treatment.
