The timing of this will vary in every case and will depend on how well the tube and valve function with age. In children where the original single o ...

... incidence of AF. The relationship between these findings and the arrhythmia are still unclear. Atrial fibrillation may occur in the absence of detectable organic heart disease, the so-called "lone AF", in about 30% of cases. The term “lone AF” or "idiopathic AF" implies the absence of any detectable ...

... that: (i) the majority of SCD cases occur in patients with preserved or moderately reduced LVEF, (ii) relatively few patients with reduced LVEF will benefit from an ICD (most will never experience a lifethreatening arrhythmic event, others have a high risk for non-sudden death), (iii) a reduced LVEF ...

... Intrafascicular tachycardia has a right bundle branch block (RBBB) left-axis configuration in 90% to 95% of cases (exit site, left posterior fascicle) and the rest have RBBB with a right-axis pattern (exit site, left anterior fascicle). This form of VT is seen in the second to fourth decade of life ...
atrial fibrillation
atrial fibrillation

... Atrial flutter is another type of arrhythmia. It is caused by very fast but regular electrical impulses that often start in the right atrium. The electrical impulses travel around and around in the atrium in an abnormal circular pattern (“circuit”). ...

... As impulses arise in SA node and traverse through atria, they cause depolarization of the atria. From the atria impulses reach AV node, where there is some delay. This delay will allow the atria to contract and pump blood into the ventricles. This impulse is later spread along bundle of His, left ...

Maintenance of sinus rhythm and treatment of atrial fibrillation Protection of the sinus rhythm in patients with MS is very important because of reduce the risk of cerebral embolism, conservation of cardiac output and exercise capacity, and reduction of symptoms. For the first time that long-term ...

The explanation is provided by a fundamental metabolic theory based on heat loss and production, the ratio of which increases as body size decreases. However, it is true that in the general po ...

Transcutaneous Pacing for Pacing
Transcutaneous Pacing for Pacing

... This technique is not as efficient as transvenous pacing because the electrical stimulus (the pads) is not in direct contact with the heart muscle. Transcutaneous pacing is a good temporary solution in an emergency situation to improve a slow heart rate resulting in inadequate cardiac output. ...

... Pacemaker syndrome refers to the occurrence of symptoms relating to the loss of AV synchrony in patients with a pacemaker, ie the atria contract at the same time as paced ventricular contractions. [4] The result is decreased cardiac output in response to which the total peripheral resistance will in ...
