Sinus arrest

Sinus arrest, also called sinus standstill, is condition that sinus node impulse can not produce. ECG showed normal PP in a significantly longer interval between the P wave occurs during the non-, or P wave and QRS wave did not occur, the PP long interval with the underlying sinus PP interval relations without multiples. Prolonged sinus arrest, the lower the potential of the pacemaker, such as the atrioventricular or ventricular junction, so that patients can be dizziness, amaurosis or short-term sense of obstacles, severe cases can occur Adams-Stokes syndrome or even death.

More young people with Sinus arrest is caused by strong vagal reflex, commonly found in pharyngeal stimulation, tracheal intubation, carotid sinus massage or the eyeball, use digitalis, quinidine sulfate and other drugs. Sometimes, inflammation, ischemia, injury, degeneration and other factors, of self-injury of the sino-atrial node cells, resulting in sinus arrest, and its varying duration, the patient will feel the heart beating for some time not a long time pause and then resume pulsatile sinus. Come to a halt after most of them in ectopic pulse, often borderline or ventricular escape beat escape beat, and sometimes for the atrial escape beat. What if, after a standstill and no emotion, that is, cardiac arrest, the patient can occur convulsions, fainting or even death. Frequent sinus arrest is a serious arrhythmia, sinus node failure is the performance, we must investigate the cause of treatment often required the installation of an artificial heart pacemaker in time.

Common causes of Sinus arrest: 1, increased vagal tone, or carotid sinus hypersensitivity. 2, acute myocardial infarction, sinus node degeneration and fibrosis, cerebrovascular disease, accidents and so on. 3, use digitalis, quinidine, potassium, acetylcholine and other drugs.

Sinus arrest Symptoms: patients with a long period of sinus arrest have dizzy, disturbance of consciousness, or even seriously convulsions.

Sinus arrest diagnosis: ECG showed normal PP in a significantly longer interval between the P wave occurs during the non-, or P wave and QRS wave did not occur, the PP long interval with the underlying sinus PP interval relations without multiples.

Sinus arrest Treatment: 1, symptomatic treatment, shorter cardioplegia may be asymptomatic; time is longer, can occur syncope, should be a timely rescue. 2, the installation of artificial cardiac pacemakers.
