I was prescribed Concor for premature ventricular contractions. Can I stop taking it if my symptoms are not severe?

 I was prescribed Concor for ventricular premature depolarization (ventricular premature contraction). I don't feel palpitations often, so can I skip taking it?

During the day, I don't feel it well because I'm active, but at night, I feel my heart pounding, so I went to the hospital and was prescribed Concor tablets.

For one of the symptoms of arrhythmia, premature cardiac contraction, if it is not properly managed with medication, as the blood flow becomes irregular, blood clots can form, and these blood clots can lead to strokes,so it is important to take it consistently and manage it.

Types of arrhythmias

Tachycardia, bradycardia, atrial fibrillation, premature cardiac contractions (atrial premature contractions, ventricular premature contractions)

What are the symptoms of premature cardiac contractions?

Arrhythmia in which the heart beats one beat earlier than scheduled

Premature cardiac contractions are divided into atrial premature contractions and ventricular premature contractions

Atrial premature contractions - when the atrium contracts early

Ventricular premature contractions - when the ventricle contracts early

The patient felt a palpitating sensation at night. Why does he feel that symptom?

It is not the premature contraction, or early contraction, that causes palpitations.

The blood that is not properly circulated due to the premature contraction mixes with the new blood that enters the heart, causing the heartbeat to become stronger.

That is why the heartbeat feels dull (you may also feel a pulse drop).

The premature contraction causes the next heartbeat to feel stronger, causing palpitations.

Are premature cardiac arrhythmias dangerous for everyone?

Premature cardiac contractions occur in 40% of healthy people, and are not dangerous in most cases. 

(In the case of premature cardiac contractions that occur without an underlying disease, the number of occurrences is important.)

In other words, premature cardiac contractions that occur without a heart disease are not dangerous in themselves.

Atrial premature contractions: Related to atrial fibrillation

- If they occur regularly more than 1,000 times a day, there is a high probability that they will progress to atrial fibrillation.

Ventricular premature contractions: Related to ventricular tachycardia

- If they occur more than 3 times in a row (non-sustained ventricular tachycardia)

- If they occur for more than 30 seconds (sustained ventricular tachycardia)

: Non-sustained ventricular tachycardia and sustained ventricular tachycardia are risk factors for sudden death.

Treatment?

1. Beta-blockers

Does not reduce the frequency of premature cardiac contractions, but reduces the size of the heart contraction, relieving palpitations

2. Reduce caffeine and alcohol, stop smoking, and be careful of overeating
