Treatment of frequent premature atrial beats

Frequent atrial premature beats are caused by mitral valve disease, which is a type of multivariate atrial fibrillation. There are many reasons for premature beats. We know that this may also happen in the hearts of some healthy people, but diseased hearts are more likely to cause atrial premature beats. The older the age, the greater the possibility of the disease. The incidence rate is relatively high between 50 and 70 years old, and it is also very harmful to patients.

Treatment of frequent premature atrial beats

1. For patients without heart disease, premature ventricular contractions do not increase their mortality. No drug treatment is required for asymptomatic isolated premature ventricular contractions, regardless of their morphology and frequency. 2. For ventricular premature beats associated with organic heart disease, the primary disease should be treated. For ventricular premature beats that require emergency treatment, 50-100 mg of lidocaine can be injected intravenously until the premature beats disappear or the total amount reaches 250 mg. After the arrhythmia is corrected, 1-3 mg can be dripped per minute as needed, and oral medication can be used to maintain stability. Lidocaine begins to work within minutes after intravenous injection and lasts for 15 to 20 minutes. Therapeutic doses have little effect on myocardial contractility, blood pressure, and atrioventricular or intraventricular conduction. Side effects include dizziness and drowsiness. Large doses can cause convulsions, respiratory or cardiac depression and may aggravate existing atrioventricular or intraventricular conduction block. Use with caution in patients with liver or kidney dysfunction or severe heart failure. 3. Ventricular premature beats caused by digitalis poisoning. In addition to drug discontinuation, IV phenytoin sodium or IV potassium chloride is often effective. For premature beats caused by hypokalemia, the cause should be actively eliminated and the hypokalemia should be corrected.

Diagnosis Premature beats may be asymptomatic or may cause palpitations or a feeling of cardiac arrest. Frequent premature beats can cause symptoms such as fatigue and dizziness (due to reduced cardiac output). For people with existing heart disease, this can induce or aggravate angina pectoris or heart failure. Auscultation may reveal irregular heart rhythm and a long compensatory interval after premature beats. The first heart sound of premature beats is often enhanced, while the second heart sound is often weakened or disappeared. When premature beats are in a binomial or tripeminic rhythm, a long pause can be heard after every two or three heartbeats. Premature beats are inserted between two regular heartbeats and may appear as three consecutive heartbeats. Palpation of the pulse may reveal intermittent absence of pulses.
