Sinus rhythm with uprightP wavesin leads II, III and aVF B. Normal, upright, narrowQRS complexes, unless concurrent conduction disorder present C. Slow sinus discharge rate: ≤60 bpm in dogs; ≤120 bpm incats D. ± Escape beats from AV node or ventricular Purkinje fibers ...
conduction originates from the AV node itself and theQRS complexremains narrow. In Mobitz type II, second-degree AV block, there is intermittent failure of conduction reaching the ventricles that is not associated with progressive prolongation of the P-R interval. There is not a shortened P-R ...
the need for pacing in asymptomatic near sustained narrow QRS type I second-degree AV block. 2. Some of the recommendations for pacing need to be presented with greater precision in concert with the above, and also to reflect current and changing clinical practice. 3. Emergence of new non-...

We encountered...
The admission ECG (Fig. 1) showed regular sinus rhythm at 95 beats/min and 2 different types of QRS complexes on alternate beats: (a) a narrow QRS complex (0.08 second) showing PR interval of 0.16 seconds and a negative T wave in the inferior leads (arrows), and (b) a wide QRS ...
Our goal was to compare acute and chronic results of two approaches to pacing in patients with permanent atrial fibrillation, narrow QRS complexes, and symptomatic bradycardia: right ventricular myocardial pacing versus HB pacing. 2 Methods Consecutive patients who received HB pacemakers were compared ...
During the 6-month follow-up, both left and right ventricular synchronies were improved, and narrow QRSd persisted in patients with BBB. Conclusion In most bradycardia patients, RBBB could be completely or partially narrowed by LBBAP at different pacing models in addition to the correction of ...
(3.09±2.34 cm2 vs.2.95± 1.92 cm2).No lead and device related complication was observed during follow-ups.Conclusions LBBP is feasible and effective in patients with bradycardia after cardiac surgery.LBBP produces narrow QRSd,which may be a preferred pacing strategy for patients after cardiac ...
