Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical axis reflects the average direction of ventricular depolarization during ventricular contraction. The direction of the depolarization (and thus the electrical axis) is generally alongside the...

like in the transitory ST changes of syndromes of coronary ischemia.The diagnosis takes into consideration the clinical, enzymatic findings as well as the above plus the ischemic T-wave changes, nonspecific ST-T wave changes, or rarely a normal ECG. ...

In patients who do not have STEMI but are suspected to have NSTE-ACS, the ECG is still an important diagnostic tool. 32% of patients with T wave inversion and 48% of patients with ST depression will have AMI, as diagnosed using serum creatine kinase (CK). Regardless of whether these pat...
absence of pathological Q waves, and no ventricular hypertrophy; 6) QTc interval in males ≤ 440 ms or females ≤ 460 ms; 7) QRS axis without deviation; 8) normal increase of R wave in precordial leads; 9) ST segment without elevation or depression; 10) smooth and asymmetric T waves....
Why might there be a left axis deviation shown in the ECG during pregnancy? Because of diaphragmatic elevation What are the ECG changes during pregnancy? - T wave inversion in leads III and aVF - ST depression - small Q waves - sinus tachycardia ...
On ECG, right axis deviation with normal sinus rhythm was seen. Ebstein Anomaly with Pregnancy: A Rare Case After an asystole episode lasting approximately 10-12 seconds, it was observed that the rhythm spontaneously turned back to normal sinus rhythm but as bradycardic. Atrioventricular Block in...
medial oblique axis The bandwidth of each channel, exceeding 10 GHz, results in a ranging resolution superior to 1 cm. High-speed 3D sensing and imaging are achieved via a parallel random LiDAR system that shows excellent resilience against cross-channel interference.Development and demonstration of...
Data at 1.5 and 3 T is now available for normal subjects using bSSFP short axis imaging. Since it has been shown that parameters of LV volumes and function do not vary by field strength, calculation of the weighted means of these parameters include studies performed at 1.5 T and 3 T [20...
