Impact of Arrhythmia in Hospital Mortality in Acute Ischemic Stroke Patients: A Retrospective Cohort Study in Northern Mexico
Stroke remains one of the leading causes of death globally. 1 In Mexico, it represents the 6th cause of death2 and contributes with 688.19 DALYs per 100,000 people,3 constituting a major cause of burden of disease in the country. Heart rhythm dysfunctions following acute ischemic strokes (AIS) have been previously reported,4 –9 and it is expected that 25-30% of patients will be diagnosed with any type of arrhythmia after stroke.6,9 Kallmünze et al. reported the incidence of several post-stroke arrhythmias, such as atrial fibrillation (AF), focal atrial tachycardia, undetermined supraventricular tachycardia, ventricu la...

Prognostic Significance of Fragmented QRS in Patients with Acute Ischemic Stroke
Stroke is a leading cause of mortality and morbidity in developed countries1 and has a strong relationship with cardiovascular system disorders.2 Due to this relationship, the connection between brain and heart has become increasingly important and neurocardiology has emerged as a popular concept over the recent years.3 Electrocardiographic abnormalities and various cardiac arrhythmias occurring especially after stroke support this phenomenon.4 ST segment and/or T-wave abnormalities without myocardial ischemia,5 left axis deviation, QT prolongation,6 QT dispersion,7 atrial fibrillation (AF), sinus tachycardia, ventricular ...

Cardiac Arrhythmias and Acute Cerebrovascular Events: A Case of QT Prolongation and Torsades de Pointes Early After Right Insular Stroke
Stroke involving some areas of the cerebral hemisphere, such as insula, amygdala, and lateral hypothalamus, may cause changes in autonomic control of cardiac function. A 58-year-old woman presented to the emergency department for acute onset of left facial-brachial-crural hemiparesis and dysarthria. A brain CT scan showed subacute ischemic lesion with hemorrhagic infarction in right insular-rolandic cortex. Over the next few days ECG showed severe bradycardia with elongation of QTc, significative pauses (5 seconds), runs of nonsustained ventricular tachycardia and torsades de pointes.

Carotid Dissection Complicated by Polymorphic Ventricular Tachycardia
In this case report, we describe a patient with fibromuscular dysplasia who suffered spontaneous bilateral carotid artery dissections. This was followed by significant variations in blood pressure and heart rates during her admission. Unfortunately, during an episode of bradycardia, a premature ventricular contraction occurred during the T wave which resulted in polymorphic ventricular tachycardia. As described in the case and in graphic depiction, this hemodynamic instability resolved after stenting of the carotid artery.
