An electrocardiogram (ECG) records the flow of electrical current on three distinct waves. Explore the purpose of an ECG, the three wave types, and the purpose of each wave on an ECG. Related to this QuestionWhat does the EKG measure? What is an ECG? What doe...
In a right bundle branch block, a tall, wide RSR pattern typically is seen on the ECG. Tall R waves indicate severe right ventricular hypertrophy when seen in certain leads of the ECG. A posterior myocardial infarction or pause in the sinus node also might cause tall R waves. The ...
There were 20 with anteroseptal or anterior MI and 4 posterior MI versus 35 controls. Autopsy findings were available in 14 cases. The sensitivity and specificity in the 20 cases were evaluated for Chapman's sign in single ECG leads. Lead I: 50 % and 5 % respectively, lead aVL: 50 % ...

Well-designed clinical studies on the palatal development in preterm and low birthweight infants are desirable because the literature is characterized by contradictory results. It could be shown that knowledge about 'normal' palatal development is still weak as well (Part 1). The objective of this...
(71–81%)). Cardiac MRI in advanced cardiac amyloidosis shows diffuse subendocardial heterogeneous enhancement in a nonvascular distribution on delayed contrast-enhanced MR images using inversion recovery technique. This, along with diffuse multichambered wall thickening, posterior right atrial wall ...

The most common indications for pacing are high-degree atrio-ventricular block (AVB) and sinus node dysfunction (SND) [3]. There is no evidence that permanent pacemaker (PPM) therapy leads to a mortality benefit in patients with SND, but there can be clear improvements in symptoms and ...
The operator manually draws EAT contours every 15 mm within a region of interest that usually includes the anterosuperior mediastinum at the pulmonary trunk level, the left main trunk, the left anterior descending and circumflex arteries in proximal segments, the posterior mediastinum, and the ...
