The main reason for this type of dislocation was postdilation in borderline high position most likely combined with
extrasystole during fast pacing.
The EKG showed sinus bradyarrhythmia, 45-60 bpm, QRS axis at -45 degrees, left anterior fascicular block, an atrial
extrasystole with incomplete compensatory postextrasystolic pause, three isolated premature QRS complexes with a right bundle branch block morphology, with rsR' aspect in V1, but with normal QRS duration (0.08 sec), which could have been either junctional
extrasystole with aberrant intraventricular conduction or ventricular
extrasystole with the origin in the proximal portion of the interventricular septum, with compensatory pauses.
When this does occur, an
extrasystole is the likely outcome.
At diagnosis of CA RCG-study allows to value the frequency of the CA, time of the appearance in diastole, quantify of the ectopic centers, differentiate the ventricular and supraventricular
extrasystole, parasystole, bi- and trigeminy, sinus dysfunction and other arrhythmias.
These arrhythmias were determined as atrial tachycardia, ventricular tachycardia, and WPW syndrome-related SVT with bradycardia due to blocked atrial
extrasystole. Arrhythmias were controlled with drugs, including propranolol, sotalol, and amiodarone (4).
Ventricular arrhythmias from simple ventricular
extrasystole to fatal ventricular tachycardia may be triggered by the contribution of impaired electrical balance of the heart and the increased sympathetic system.18,19 In light of this information, it is important to evaluate the Tp-e interval, Tp-e dispersion, Tp-e/QT and Tp-e/QTc ratios, which are known to be associated with an increased risk of cardiac arrhythmia and which are relatively newly defined parameters of transmyocardial repolarization in diabetic patients.17,18 In this study, it was shown that Tp-e interval, Tp-e dispersion, Tp-e/QT and Tp-e/QTc ratios were longer in the T2D cases than those in the control group.
However, ventricular
extrasystole with a 2:1 response developed in one patient and bronchospasm in another.
However, during each attempt to get up, we registered atrial fibrillation or individual SVES (supraventricular
extrasystole) and VES (ventricular
extrasystole) triplets.
In the study, we define the term, extrasystolic coverage, as the fraction of time in a 24 h ECG recording, where at least one
extrasystole has occurred within the preceding 30 minutes, see Figure 1 for further explanation.
Electrocardiographic abnormalities have been noted in 38-91% of cases and include bundle branch block (right, left) in 25%, atrioventricular block in 8%, atrial fibrillation in 2-6%,
extrasystole (atrial and ventricular) in 18% and ventricular fibrillation in 2%.4 In the above series, case 3 died of ventricular fibrillation and case 5 had extensive conduction block.
Three of the most common ectopic beats are premature ventricular contraction (PVC), premature atrial contraction (PAC) and
extrasystole.
