ectopic focus मीनिंग इन हिंदी

उदाहरण वाक्य

1. In some cases ablation of the ectopic focus may be necessary.
2. An AV junctional escape is a delayed heartbeat originating from an ectopic focus somewhere in the AV junction.
3. Any part of the heart that initiates an impulse without waiting for the sinoatrial node is called an ectopic focus and is, by definition, a pathological phenomenon.
4. This may cause a single premature beat now and then, or, if the ectopic focus fires more often than the sinoatrial node, it can produce a sustained abnormal rhythm.
5. The resulting heart rhythm depends on where the first signal begins : If it is the sinoatrial node, the rhythm remains normal but rapid; if it is an ectopic focus, many types of dysrhythmia may ensue.
6. The cause of the arrhythmia, the ectopic focus, is usually near the AV node in the triangle of Koch ( a rough triangle with points at the coronary sinus, the tendon of Todaro, and the tricuspid valve ).
7. Rhythms produced by an ectopic focus in the atria, or by the atrioventricular node, are the least dangerous dysrhythmias; but they can still produce a decrease in the heart's pumping efficiency, because the signal reaches the various parts of the heart muscle with different timing than usual and can be responsible for poorly coordinated contraction.
