5]  One should try to avoid the use of dexmedetomidine in presence of bradyarrhythmias
, severe left ventricular/biventricular dysfunction and hypovolemic states.
in patients with sleep apnoea: the effect of continuous positive airway pressure treatment: a long-term evaluation using an insertable loop recorder.
Nevertheless, some concerns have been raised related to other side effects due to adenosine receptor blocking effects (RESPOND study) almost 15% of patients referred had dyspnoea or bradyarrhythmias
compared with 8% with prasugrel.
Arrhythmias other than sustained ventricular tachycardia, including multifocal PVCs, triplets of PVCs, supraventricular tachycardia, heart block, or bradyarrhythmias
Groups at increased risk for torsades de pointes are those with known prolongation of the QT interval, history of torsades de pointes, congenital long QT syndrome, bradyarrhythmias
, or uncompensated heart failure, as well as those on drugs known to prolong the QT interval, those with ongoing proarrhythmic conditions, those with clinically significant bradycardia, and patients treated with class IA (quinidine, procainamide) or class III (dofetilide, amiodarone, sotalol) antiarrhythmic drugs.
In addition to the dosage change, caution is recommended in administration of Zofran to patients with congenital long QT intervals, patients with congestive heart failure, those with bradyarrhythmias
, or those taking other medications which prolong QT intervals.
The morphology of the GT interval predicts torsade de pointes during acquired bradyarrhythmias
Cardiovascular problems (such as bradyarrhythmias
, tachyarrhythmia, vasovagal syndrome, and hypotension) can place a person at risk (AGS, 2010).
The 2011 warning also stated that citalopram should not be used in patients with congenital long QT syndrome, and that patients who have congestive heart failure or bradyarrhythmias
, or are predisposed to hypokalemia or hypomagnesemia because of concomitant illness or drugs, are at higher risk of developing the arrhythmia.
in patients with OSA are related to the apnoeic episodes and over 80% are found during REM sleep.
Relation of daytime bradyarrhythmias
with high risk features of sleep apnea.
Thus, her symptomatic bradycardia was no surprise, and similar cases of severe bradyarrhythmias
have been described in patients on similar drug combinations.
They teach the interpretation of ECGs, beginning with anatomy and physiology of the heart, how the ECG is constructed, understanding the normal ECG, and steps for interpretation, then provide clinical examples of real ECGs of major cardiac conditions such as bradyarrhythmias
, ectopic beats, atrial arrhythmias, tachyarrhythmias, ischemia and infarction, and inherited arrhythmia problems.
However, her condition deteriorated promptly with ventricular bradyarrhythmias
and she died 14 hours after ingestion during hemodialysis.
Consider frequent electrocardiogram monitoring for patients with congestive heart failure or bradyarrhythmias
, or those on concomitant medications that prolong the QT interval.
