Atrioventricular junction An AV-junctional rhythm, or atrioventricular nodal bradycardia, is usually caused by the absence of the electrical impulse from the sinus node. This usually appears on an electrocardiogram (EKG) with a normal QRS complex accompanied with an inverted P wave either before, during, or after the QRS complex.

Se hela listan på textbookofcardiology.org Neurogenic bradycardia - occurs with various neurogenic diseases, which contribute to the slowdown of cardiac activity. It may be neuroses and depression, diseases of the gastrointestinal tract, cerebral pathology.

SINUS Bradycardia Bradyarrhythmia Symptoms Causes Diagnosis with Treatment The pacemaker of the heart is the sinoatrial node (SA node). The number one primary cause of bradyarrhythmias is aging leading to fibrosis and degeneration of the conduction system and pacemaker cells.

A cardiac arrest can cause damage to the tissue of the heart. What causes sinus bradycardia? A number of conditions can cause sinus bradycardia. In some cases, the cause is not known. When sinus bradycardia causes problems, it is called pathophysiologic sinus bradycardia.

This is mainly due to age-related changes, a decrease in the reactivity of the organism, an increased level of excitability, neuropsychiatric overstrain, stress, a change in the hormonal background, a general restructuring of the body, and a violation of the body mass index (the relationship between height and weight).
