Premature ventricular contractions that always occur around 7 p.m. need to be investigated for the cause and necessary intervention or treatment. Around 7 p.m. is usually a more strenuous time of the day, and it is even more likely to strike in patients with heart disease. The causes of premature ventricular contractions can be physiologic, pathologic, or pharmacologic. 1. Physiological premature ventricular contractions: normal people can also have premature ventricular contractions, generally not too frequent, not more than 5-6 per minute, can feel palpitations or throat feeling, without much discomfort, may be associated with fatigue, stress, bad mood, etc., generally do not have to deal with special treatment, rest and relaxation can be restored to normal. 2. Pathological premature ventricular contractions: for people with heart disease, such as rheumatic valvular disease, coronary heart disease, hypertensive heart disease, myocarditis and so on, there are often frequent premature ventricular contractions or other cardiac arrhythmias, need to actively treat the primary disease, and at the same time, can be given to the mesirelix, metoprolol tartrate, stabilizing the heart particles and so on to ease. 3. Pharmacological premature ventricular contractions: common in the long-term use of digitalis drugs, antidepressants, etc., can cause premature ventricular contractions, in addition to electrolyte disorders, can also appear premature ventricular contractions. Therefore, for ventricular premature beats around 7:00 p.m., it is necessary to go to the hospital in a timely manner to find out the cause, under the guidance of the doctor targeted treatment.
