For patients with more than 1,000 PVCs per day, the risk of developing left ventricular systolic dysfunction after 5 years follow-up is low. Frequent PVCs may increase the risk of developing cardiomyopathy, which can greatly impair heart function. A PVC burden greater than 10% is the minimal threshold for development of PVC-induced cardiomyopathy.
Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).
Premature heart beats can be asymptomatic (the patient does not complain about anything). The subject may experience palpitations, a feeling of cardiac "pause". Taking (prolonged) pulse may result in a rhythm that seems irregular. Electrocardiography and laser Doppler imaging [3] allow to visualize premature heart beats. From their appearance ...
The link between anxiety and palpitation may also explain why many panic attacks involve an impending sense of cardiac arrest. Similarly, physical and mental stress may contribute to the occurrence of palpitation, possibly due to the depletion of certain micronutrients involved in maintaining healthy psychological and physiological function.

With appropriate care from adults, young children can easily cope with tolerable stress and turn it into positive stress. However, if adult support is deficient in a child's coping stages, then tolerable stress can become detrimental. [4] Toxic stress can occur when experiences are long in duration and intensity. [14]
[4] Children during their developmental stages experience fears. Fear is a natural part of self-preservation. Fears allow children to act with the necessary cautions to stay safe. [5] According to Child and Adolescent Mental Health, "such fears vary in frequency, intensity, and duration; they tend to be mild, age-specific, and transitory."
Bigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat.Most often this is due to ectopic beats occurring so frequently that there is one after each sinus beat, or normal heartbeat.
Like adults, children can experience anxiety disorders; between 10 and 20 percent of all children will develop a full-fledged anxiety disorder prior to the age of 18, [107] making anxiety the most common mental health issue in young people. Anxiety disorders in children are often more challenging to identify than their adult counterparts, owing ...
