The main reason for this type of dislocation was postdilation in borderline high position most likely combined with extrasystole during fast pacing.

Failed TAVI in TAVI Implantation: TAVI Dislocation Followed by Ensuing Surgical Graft Resection

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.

Sick sinus syndrome--a case report of paroxysmal supraventricular tachycardia due to atrioventricular node re-entry

When this does occur, an extrasystole is the likely outcome.

A serious and repeatable electrical hazard--compressed electrical cord and an operating table

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.

Possibilities of high-resolution HRV analysis

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).

An Extremely Rare Cause of Wolff-Parkinson-White Syndrome: Rhabdomyoma in Association With Tuberous Sclerosis

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, 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.
