Workup

Wide QRS Complex
  • Note that other causes of wide QRS complex must always be considered. For example, Wolff-Parkinson-White syndrome (WPW), pacemaker stimulated beats, electrolyte imbalance and medications may prolong the QRS complex.[ecgwaves.com]
  • […] bundle type) preceding a wide QRS complex.[rjmatthewsmd.com]
  • Treat a wide QRS complex tachycardia like ventricular tachycardia until proven otherwise. The TIMI Risk Score should be used to predict outcomes in patients presenting with potential anginal symptoms.[healio.com]
  • A wide QRS complex and/or a rate of 20 to 40 bpm imply a block in the His-Purkinje system, which is most often the case in acquired AV blocks. 60. Figure 6.[revespcardiol.org]
Prolonged QT Interval
  • Antiarrhythmics Anti-arrhythmics: These may lead to several ECG-changes; Broad and irregular P-wave Broad QRS complex Prolonged QT interval (brady-, tachycardia, AV-block, ventricular tachycardia) Prominent U-wave In case of intoxication, the above mentioned[en.ecgpedia.org]
  • An acute intracranial process (hemorrhage, trauma, carotid endarterectomy etc...) can cause dramatic T wave inversions and a prolonged QT interval on the ECG.[healio.com]
  • Administration of intravenous magnesium sulfate to patients with prolonged QT intervals and torsades de pointes, whether the initial Mg level is normal or low, may suppress the ventricular arrhythmia.[rjmatthewsmd.com]

  • Trastuzumab, used in the treatment of metastatic breast cancer, can cause a cardiomyopathy.[clevelandclinicmeded.com]
  • Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery.[icdlist.com]
