Does the Magnitude of the Electrocardiogram QT Interval Dispersion Predict Stroke Outcome?

QT dispersion, maximal interlead difference in QT interval on 12-lead electrocardiogram (ECG), measures cardiac repolarization abnormalities. Data are conflicting whether QT dispersion predicts adverse outcome in acute ischemic stroke (AIS) patients. Our objective is to determine if QT dispersion predicts: (1) short-term clinical outcome in AIS, and (2) stroke location (insular versus noninsular cortex).

Stroke may be the first manifestation of previously undetected AF. Given the efficacy of oral anticoagulants in preventing AF-related ischemic strokes, strategies of searching for AF after a stroke using ECG moni...

In conclusion, about one-third of the patients with AF did not regularly see a doctor in a medical institution and most of them had a CHADS2 score of more than one point in a Japanese rural area. Educating the public about the risks of AF is required. PMID: 31735770 [PubMed - as supplied by publisher]

Written by Meyers, edits by SmithA 50-ish year old man was working construction when he suddenly collapsed. Coworkers started CPR within 1 minute of collapse. EMS arrived within 10 minutes and continued CPR and ACLS, noting alternating asystole and sinus bradycardia during rhythm checks. He received various ACLS medications and arrived at the ED with a perfusing rhythm.Initial vitals included heart rate around 100 bpm and BP 174/96. Here is his initial ECG, very soon after ROSC:What do you think?Sinus tachycardia.  There is incomplete RBBB (QRS duration less than 120 ms).  There is diffuse STD, maximal in V4-V5 a...

A 68-year old man with a history of hypertension, diabetes, coronary artery disease and an obliterating lower limbs arteritis, presented for a stroke. Electrocardiogram did not show atrial fibrillation nor ischemic electrocardiographic signs. White blood cell count (10800/m3) was high but eosinophil count (234/mm3) was normal. Atherosclerosis origin of the stroke was suspected.

Conclusions. Certain types of arrhythmias such as APC, VPC, SVT and paroxysmal AF have been shown to be independently associated with the presence of ASA. PMID: 31544553 [PubMed - as supplied by publisher]

This study aimed to evaluate the relationship between transmyocardial repolarisation parameters and the size of the diffusion limitation area measured using diffusion weighted magnetic resonance imaging (DWMRI) in patients diagnosed with ischaemic stroke without known cardiac diseases. MATERIAL AND METHODS: The study was a prospective, observational clinical study. Patients without cardiac disease with acute ischaemic stroke were included in the study. Electrocardiography (ECG) was received from the patients. P, QT, QTc and Tp-e dispersions were calculated. All the patients had computerised brain tomography (CT) and t...

Abstract Introduction: Various factors such as age and severity of the stroke have been deemed connected with risk of mortality in patients with acute ischemic brain stroke. The present study was performed with the aim of evaluating the role of electrocardiogram (ECG) changes in predicting the outcome of these patients. Methods: In this cohort study, patients who had presented to the emergency department of a teaching hospital during 1 year and were diagnosed with acute ischemic stroke were evaluated. Demographic data and 12-lead ECG findings of the patients were gathered and their relationship with 1-year mo...

Conclusions: In this single center study of mostly lean patients, percutaneous closure of PFO under TTE guidance as the only imaging tool appeared effective at midterm follow-up, while avoiding radiation exposure, endotracheal intubation and contrast agent use. PMID: 31372266 [PubMed]

CONCLUSION: Subclinical NOAF is common after TAVR, usually occurs months after hospital discharge, and is associated with lack of anticoagulation therapy and increased risk of stroke. Prolonged surveillance of subclinical NOAF may be warranted after TAVR. PMID: 31257211 [PubMed - in process]

In conclusion, the PULVAD unloads the failing LV, optimizes LV mechanoenergetics, and augments coronary blood flow. These salutary effects of short-term PULVAD support provide the foundation for long-term testing.
