WebSep 5, 2006 · An isoelectric P-wave in lead V 1 was associated with a specificity and a PPV of 100% and an NPV of 97% for perinodal and right septal tachycardias, but the sensitivity was only 50% (Table 3). A negative, then positive P-wave in V 1 was present in 3 of 3 left septal tachycardias and in 1 of 7 perinodal tachycardias. In the remaining ECG leads ... WebDuring ablations we observed on the surface ECG a progressive modification of the second component of the P wave (delayed and then negative in inferior leads). These findings …

Normally, the QRS interval is 0.07 to 0.10 second. An interval of 0.10 to 0.11 second is considered incomplete bundle branch block or a nonspecific intraventricular conduction delay, depending on QRS ...

As the PICC tip approaches the sinoatrial node at the CAJ, P wave starts to elevate and reaches the maximum height at the CAJ. When it passes through into the RA, the P wave starts to invert, indicating ...
