Below: Rhythm strip lead II with atrial pacing (Ap), LV stimulus artefact and RV stimulus artefact, 60 milliseconds later. There is a latency period between the atrial stimulus artefact and the paced P wave (red highlight). Sign in to download hi-res image Figure 6. Electrocardiograph (ECG...

In conjunction, calcium-handling protein expression was examined in left ventricular samples obtained from end-stage HF patients, in patients with either persistent atrial fibrillation or sinus rhythm. Compared with regularly paced ventricular cardiomyocytes, in cells paced irregularly for 24 hours, there...
Asynchronous atrial and ventricular beats and rapid ventricular rhythm → ↓ blood flow into the ventricle during diastole→ ↓ cardiac outputConsequent hemodynamic compromise → symptoms of syncope, MI, anginaReference [3]Clinical features Often asymptomatic, especially in NSVT Cardiovascular features ...
During a six-month follow-up, he felt well, his functional capacity was NYHA class II, and his basic rhythm was widened QRS arrhythmia with a rate of 20 beats/min. To the best of our knowledge, atrial electrical inactivity together with right-heart failure and pericarditis confined to the ...
The presence of ectopic P waves, usually absence of full compensatory pause (R-R interval containing the premature contraction is < 2 times the R-R interval of basic rhythm), and a relatively narrow QRS complex morphology help differentiate atrial premature complexes from PVCs. The compensatory pa...
and an ECG acquired within 30 days of the CMR examination. Exclusion criteria were ECG confounders such as atrial fibrillation or flutter, abundant premature ventricular contractions (bigeminy/trigeminy), paced rhythm, hypertrophic cardiomyopathy, congenital heart disease, Takotsubo cardiomyopathy, amyloidosis...

We evaluated baseline QT interval during atrial pacing at a cycle length of 600 ms and the paced QT interval during right ventricular (RV) stimulation at the same cycle length. The QT interval was then corrected for heart rate by using the Bazett formula. Measurements during pacing were ...
