Can a cold cause premature heart beats?

If a person has symptoms of arrhythmia, it may cause palpitations, among which premature heart beats are a major manifestation of arrhythmia. There are many different types of premature heart beats, and each type is mainly distinguished according to the cause of the premature heart beats. When people have a cold, some people who are already weak are prone to develop symptoms that are not caused by a cold. So will this trigger symptoms of premature heart beats in people with a cold?

Can a cold during pregnancy cause premature beats?

It is not uncommon to have ventricular premature beats and atrial premature beats during pregnancy. The risk assessment of ventricular premature beats depends largely on the function of the heart and the presence or absence of other organic heart diseases. Your ultrasound shows that your heart structure and function are normal, so even if you have a lot of premature beats, no special treatment is needed (premature beats are benign). If you have obvious palpitations, chest tightness, etc., you may consider using beta-blockers (such as bisoprolol, etc.). Although this drug can cross the placenta, it is generally safe to use in the second trimester of pregnancy. If you do not feel any obvious discomfort, medication is not necessarily recommended. You should pay attention to rest, prevent colds, maintain a good mood, and eat more fruits and vegetables.

It has little impact on the fetus, and whether to perform a caesarean section does not depend on the number of premature beats.

Premature beat is also called premature contraction, extrasystole, or premature beat for short. It is a premature ectopic heart beat, which can be divided into four types according to the site of origin: sinus, atrial, atrioventricular junction and ventricular. Among them, ventricular is the most common, followed by atrial. Premature sinus beat is rare. Premature beat is a common ectopic heart rhythm. It may occur in the setting of sinus or ectopic (eg, atrial fibrillation) rhythm. It may occur sporadically or frequently, and may occur irregularly or regularly after every or every few normal beats, forming bigeminy or coupled premature beats.

What are the treatments for premature beats?

The main goal of treating ventricular premature beats is to prevent ventricular tachycardia, ventricular fibrillation, and sudden cardiac death.

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.

4. If ventricular premature beats occur during quinidine syncope or antimony treatment, quinidine or antimony should be discontinued immediately.
