This study aimed to investigate the relationship between levels of anxiety and burnout and the prevalence of atrial extrasystoles (AESs) and ventricular extrasystoles (VESs) among critical care nurses.
Holter ECG device Syneflash Card MinHR/24h revealed findings composed of an hour intervals of the heart-rate, pause, missed beats, supraventricular extrasystoles (isolated and couplet), ventricular extrasystoles (isolated and couplet), total extrasystoles and ST segment deviations each.
9-11,13 Altered load changes myocardial segment length that, acutely, can result in decreased resting potential and the occurrence of after-depolarizations that cause extrasystoles in the region of greatest stretch.
The susceptibility to ventricular arrhythmias can be explained by the imbalance of currents creating a vulnerable window during which time an extrasystole can trigger a phase 2 re-entry arrhythmia (9).
Frequent ventricular extrasystoles during exercise indicate underlying cardiac disease [13].
Twelve patients had hemodynamic instability that required vasoconstrictors and 6 had arrhythmias, mainly supraventricular and ventricular extrasystoles.
2002) Increasing plasma potassium with amiloride shortens the QT interval and reduces ventricular extrasystoles but does not change endothelial function or heart rate variability in chronic heart failure.

The investigators found 55% were in sinus rhythm and 43% had isolated extrasystoles.
