Atrial Fibrillation in the Critically Ill Patient

…ischaemic electrocardiographic changes during rapid AF. ST segment depression or T wave inversion can occur without coronary artery disease. Proposed explanations in the source material…

The ECG in assessment of myocardial reperfusion

…ECG are assessed: Normalization (return) of ST segment elevations Rapid T wave inversion Normalization (return) of ST segment elevations Successful reperfusion results in rapid and…

Quiz: ECG in athletes

…B: Prolonged QT interval (QTc ≥ 480 ms for females) C: Incomplete Right Bundle Branch Block (rSR' pattern in lead V1 and qRS pattern in V6…

The T-wave: physiology, variants and ECG features

…after infarction and after successful reperfusion (PCI). Post ischemic T wave inversion is caused by abnormal repolarization. These T wave inversions are symmetric with varying…

Arrhythmogenic Right Ventricular Cardiomyopathy / Dysplasia (ARVC, ARVD)

…leads to ventricular dilation and right heart failure. Biventricular heart failure is less common. ECG in ARVC T wave inversion in the lead V1 through…

Brugada syndrome: ECG, clinical features and management

…dyspnea (10%). The major ECG findings in ARVC are T wave inversion in V1–V3 (in the absence of right bundle branch block); virtually all…

Classification of Acute Coronary Syndromes (ACS) & Acute Myocardial Infarction (AMI)

…Figure 2 (below) displays ST segment depression, ST segment elevation and T wave inversion. These ECg changes will be discussed in great detail in the…

ECG in myocardial ischemia: ischemic changes in the ST segment & T-wave

…rather common, particularly in women. The T wave inversion is concordant with the QRS complex. Leas V7–V9 : should display a positive T wave. ST…

Pre-excitation, Atrioventricular Reentrant (Reentry) Tachycardia (AVRT), Wolff-Parkinson-White (WPW) syndrome

…wave, meaning that a positive delta wave will be followed by a negative ST T segment (typically with ST segment depression and T wave inversion)…

T-waves in ischemia: hyperacute, inverted (negative), Wellen's sign & de Winter's sign

…displays a negative T wave in adults. III and aVL may occasionally display an isolated (single) T wave inversion. The term isolated implies that none…
