Others include ventricular septal defect, single atrium, tetralogy of Fallot, coarctation of aorta and anomalous pulmonary venous return.4 This condition is also associated with various conducting system abnormalities such as tachyarrhythmias (supraventricular tachycardias, atrial fibrillation/flutter) or bradyarrhythmias (atrioventricular and intraventricular conduction blocks).5,6 The most easily available modality to diagnose PLSVC is transthoracic echocardiography.
CVS manifestations can exhibit a wide spectrum at every stage, ranging from signs of stimulation (hypertension, tachyarrhythmia) to depression (hypotension, bradyarrhythmia, cardiac arrest).
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.
Prevention and management of AV blocks and bradyarrhythmia are very important, because they cause AV dyssynchrony leading to loss of atrial contribution to ventricular filling further jeopardising already decreased cardiac output.
Thoracic auscultation revealed crackles in lung area and heart bradyarrhythmia.
The mechanism of bradyarrhythmia due to ticagrelor is not well established.
In CCB overdose, cardiovascular collapse, heart block, bradyarrhythmia and hypotension, hyperglycemia, lactic acidosis, seizures, coma, and non-cardiogenic pulmonary edema and intestinal ischemia may occur (1,3, 9).
Participants were excluded from the current analysis for the following reasons: inadequate urine sample volume for metals assays (n = 465); bradyarrhythmia (heart rate < 40 beats/min) or tachyarrhythmia (heart rate > 100 beats/min) (n = 348), consistent with a previous study (Magari et al.

The symptoms of bradyarrhythmia are most commonly intermittent syncope or presyncope but may be general and nonspecific.
Temporary epicardial pacing is commonly indicated in cardiac surgical patients, when right ventricular (RV) and/or right atrial (RA) pacing wires are used to prevent postoperative bradyarrhythmia and atrioventricular (AV) block.
Two hours after the second dose, she developed a junctional bradyarrhythmia with the heart rate slowing from 101 to 34 beats/minute and hyperkalaemia up to 6.8 mmol/l.
It may also manifest in the form of tachyarrhythmia, bradyarrhythmia, heart failure, thromboembolism or sudden death.
Bradyarrhythmia and sinus pauses are commonly described in patients with OSA.
The possible causes of tachyarrhythmia and bradyarrhythmia following the Fontan procedure may include damage to the sinoatrial (SA) node or the artery, extensive atrial suture lines and incisions, and exposure of the atrial myocardium to prolonged high pressure.
