Since wavelet analysis is an effective tool for analyzing transient signals, we studied its feature extraction and representation properties for events in electrocardiogram (EKG) data. Significant features of the EKG include the P-wave, the QRS complex, and the T-wave. For this paper the feature that we chose to focus on was the P-wave. Wavelet analysis was used as a pre-processor for a backpro...

ST segment elevation is associated with non-cardiac pathologies but is not as well reported as myocardial infarction. We present a case of a 63-year-old man who was admitted for an overdose on cyclobenzaprine with signs of anti-cholinergic toxicity. He developed signs of ileus on imaging and became progressively obtunded. He was noted to have ST segment elevations on electrocardiogram (EKG) wit...

Electrical noise will be present in the operating room even under ideal circumstances. The addition of the cardiopulmonary bypass machine to the other machinery in the operating room introduces one more source of electrical noise. Identifying and managing this interference may aid in reducing artifactual signals on the electrocardiogram (EKG) monitor. If electrical interference occurs during th...

Cutaneous leishmaniasis (CL) has been recognized as a major public health problem in several countries. It is highly endemic in the north and east Mediterranean regions in the Syrian Arab Republic with more than 75.9% of all CL cases recorded from these regions. Pentavalent antimonials have been considered as standard treatment for leishmaniasis. Use of pentavalent antimonials to treat leishman...

A routine EKG during admission for gastrostomy in a chronically hypertensive 75-year-old patient with amyotrophic lateral sclerosis (ALS) demonstrated repetitive small depolarizations (figure). The patient had no cardiac pacemaker and was not taking any medication. A study of 550 routine EKGs revealed somatic muscle fasciculation potentials in 1%, in association with a range of lower motor neur...
