Why is the QRS complex larger than the P wave? Describe the ECG changes seen in atrial fibrillation. What event(s) should occur during a QRS interval on an EKG? The second heart sound (dub) is correlated with which ECG wave? Give the definitions of the P wave, QRS complex, T w...
What happens to the duration of the QRS complex on an electrocardiogram when heart rate increases due to exercise? What does the T wave on an ECG represent? The rapid depolarization of the ventricles during the cardiac cycle is measured in the? A) P wave B) QRS complex C) T wave D...
Hospitalised patients should be discharged once stable for 48 hours on optimal medical therapy. All pertinent clinical information, including aetiology and echocardiographic evidence for HF, major comorbidities, electrocardiography parameters (rhythm, QRS duration, morphology or paced), peptide level, discharg...
Additionally, when a LV lead could not be placed, crossover was also permitted. Crossover occurred in 48% of the HBP group, and 26% of the BiV pacing group. The HBP group demonstrated a statistically greater reduction in QRS duration, although the between-group difference was not significant...
Both sexes benefited from CRT with a QRS duration of 150 ms [16]. 6. Does a Gender-Related Issue Exist in Heart Failure? The decision to focus on sex-based differences, specifically referring to biological characteristics, in this study was motivated by the current limited understanding of ...

19 If signals are poor, basket repositioning should be attempted (see below). Focal Impulse and Rotor Mapping (FIRM): Technical Approach and Limitations Figure 3 summarizes the workflow for FIRM mapping and ablation. For macro-reentry, ablation would aim to bisect circus movement...
Polymorphic ventricular tachycardia (PVT) is a type of abnormally fast heart with a continuously varying QRS complex morphology in an electrocardiogram. Therefore, QRS complexes vary in amplitude, axis, and duration in PVT. When ventricular tachycardia originates in different places around the ...
whether it should be categorized as T2 wave or a U wave), the T-wave offset should be measured both at the nadir of the two waves (1) and at the final return to baseline (2). Adjustment for Heart Rate The time–duration intervals are influenced by heart rate (R–R cycle ...
