an electrocardiogram (ecg) leads physicians to diagnose many potentially life-threatening cardiac, metabolic, electrolyte, and toxicological conditions. this study was designed to evaluate the competency of emergency medicine residents (emrs) in comparison with cardiologists in the interpretation of ecg when an interpretation checklist is used. this clinical trial was done in the emergency ward...

abstract background: brugada syndrome (bs) is an inherited ion channelopathy characterized by an electrocardiographic (ecg) pattern of a coved type st segment elevation in right precordial leads with or without right bundle branch block. case presentation: a 23-year old male presented with right lower quadrant abdominal pain. further evaluation revealed a diagnosis of acute appendicitis. the pa...

introduction atrial standstill is a rare condition, characterized by absence of atrial electrical and mechanical activity evident in surface electrocardiography echocardiography, or fluoroscopy, which is associated with unresponsiveness of atria to maximal output electrical stimulation. this condition can be present with thromboembolic complication, low cardiac output, and sometimes palpitation...

1. The influence of different water temperatures on the electric organ discharge (EOD) of a mormyrid fish Marcusenius cyprinoïdes was studied. The range of the water temperatures was fixed according to the seasonal temperature variations of the rivers in Central Africa, the natural habitat of this species. 2. The EOD activity was characterized using the following parameters: mean EOD rate, EOD ...

Let EG be a stable principal G–bundle over a compact connected Kähler manifold, where G is a connected reductive linear algebraic group defined over C. Let H ⊂ G be a complex reductive subgroup which is not necessarily connected, and let EH ⊂ EG be a holomorphic reduction of structure group. We prove that EH is preserved by the Einstein–Hermitian connection on EG. Using this we show that if EH ...

Let M be an irreducible projective variety over an algebraically closed field k of characteristic zero equipped with an action of a group Γ. Let EG be a principal G–bundle over M , where G is a connected reductive algebraic group over k, equipped with a lift of the action of Γ on M . We give conditions for EG to admit a Γ–equivariant reduction of structure group to H , where H ⊂ G is a Levi sub...

electrocardiogram (ecg) is one of the most common biological signals which plays a significant role in diagnosis of heart diseases. one of the most important parts of ecg signal processing is interpretation of qrs complex and obtaining its characteristics. r wave is one of the most important sections of this complex which has an essential role in diagnosis of heart rhythm irregularities and als...

introduction to extract and combine information from different modalities, fusion techniques are commonly applied to promote system performance. in this study, we aimed to examine the effectiveness of fusion techniques in emotion recognition. materials and methods electrocardiogram (ecg) and galvanic skin responses (gsr) of 11 healthy female students (mean age: 22.73±1.68 years) were collected ...
