Ventricular potentials are considered to be late ventricular potentials. Positive can check the cause, life regulation and drug treatment. 1. Check the cause:Late ventricular potential is the late electrical activity of the heart muscle reflected by the superimposition of body surface information onto the electrocardiogram. If it is positive, it means that myocardial electrical activity is unstable, which may be related to myocarditis, myocardial injury, arrhythmia and other causes. Further examination of cardiac ultrasound, CT, coronary angiography and other items are needed to find the cause. 2. Life management: patients with positive ventricular late potentials should combine work and rest, do not take alcohol, tea, coffee and other excitatory nerves and lead to accelerated heart rate and food, do not stay up late at night, to avoid excessive exertion, and to maintain emotional well-being. 3. Drug therapy: patients with positive ventricular late potential, if combined with arrhythmia, you can take lidocaine, amiodarone and other anti-arrhythmic drugs; if combined with tachycardia, you can take propranolol, metoprolol tartrate and other drugs, but low blood pressure, allergic to drugs is not recommended to take the patient. Specific medication should follow the doctor’s instructions. If the phenomenon of positive ventricular late potential, it is not recommended to use the drug by oneself, it is recommended to go to the hospital to check the cause of the cause under the guidance of the doctor for treatment.
