b, a second ecg the following day shows a slightly faster sinus rate, shorter pr intervals, and normal, nonpaced qrs complexes. there are deep negative t waves in the inferior leads and in the anterolateral chest leads. leads i and avl are spared. memory t waves are very common in ...
It is suggested, on the basis of the experimental results of cooling or warming the endocardial surface of the dog's left ventricle, that large, upright T waves in the human electrocardiogram, together with prolongation of the Q-T interval, may oftent be due to ischemic changes preponderant...

Electrocardiogram (ECG) showed VT. Despite amiodarone and lidocaine administration VT persisted. After the cardioversion (CV) the rhythm became sinus and in the right precordial leads inverted T waves were present. Transthoracic echocardiography (TTE) showed two large aneurysms divided by a septum in...
MC-SleepNet extracted several features that are not directly related to sleep stages. Specifically, some filters were optimized to extract waves that are neither theta waves nor delta waves. These waves might be related to individual differences and noise in EEG signals. By using such features, ...
Repeat ECG 8 hours later still showed a ventricular paced rhythm but now with large, almost giant negative T waves in the chest leads with more shallow negative T waves in the inferior leads (Fig. IB). The patient did not experience any cardiac symptoms during the time interval between the...
The energy cutoff of the plane waves was set to 500 eV with the energy precision of 10−6 eV. The Brillouin zone was sampled by using a 21 × 21 × 1 Gamma-centered Monkhorst-Pack grid. The vacuum space was set to 20 Å to minimize artificial interactions ...
