What should you pay attention to when you have premature heart beats? Beware of these complications!

Premature beats can cause the heart to beat irregularly, which is called arrhythmia. If premature beats are not treated in time, or if good nursing care is not given during treatment, some complications of premature beats may occur, which is something that patients with premature beats need to pay attention to.

1. Ventricular tachycardia

Ventricular tachycardia refers to a tachycardia composed of 3-5 or more wide and deformed QRS waves originating below the bifurcation of the His bundle. It is similar to paroxysmal supraventricular tachycardia in form, but the symptoms are more severe. Children may be irritable, pale, and have rapid breathing. Older children may complain of palpitations and precordial pain. Severe cases may experience syncope, shock, and congestive shock. Those with short attacks have mild hemodynamic changes, while those with attacks lasting more than 24 hours may have significant hemodynamic changes. Physical examination reveals an increased heart rate, often above 150 beats/min, with a regular rhythm and heart sounds of varying strengths.

2. Ventricular fibrillation (VF)

It is caused by many intersecting reentrant electrical activity waves, and its electrocardiogram shows a chaotic recording curve. VF can often be fatal unless defibrillated with direct current (which is difficult to achieve with chest blows or antiarrhythmic drugs).

3. Sudden cardiac death

Sudden death is a clinical syndrome, which refers to the sudden and unexpected death of a person who seems to be healthy or whose condition has basically recovered or stabilized. Most of them occur within one hour after the acute onset of the disease, and the longest does not exceed 6 hours. It is mainly caused by primary ventricular fibrillation, ventricular arrest or electromechanical separation, which leads to the sudden cessation of effective cardiac contraction function.
