The relationship between luminal stenosis measured by coronary CT angiography (CCTA) and severity of stress-induced ischemia seen on single photon emission
Therefore, this study aimed to evaluate the correlation between short-term HRV and myocardial ischemia during EST, including the acceleration, maximum, and recovery stages of heart rate (HR). 2. Materials and Methods 2.1. Study Population After excluding ECG abnormalities including LBBB, paced ...
Similarly, low-cost remote Electrocardiogram (ECG) monitoring was prototyped as well [7]. The continued development in the following decades has led to more integrated systems in tele-rehabilitation and other domains, such as [8]. The need to provide remote real-time healthcare services that go...
They do not diagnose cardiovascular disease by recording a 12-lead ECG but rather focus on the changes that occur continuously and over time, observing a small number of lead ECGs. Changes in the waveform may indicate certain cardiovascular events, such as myocardial ischemia or electrolyte ...
[67,68] Such microvascular occlusions could provoke local ischemia in the myocardium as has been suggested to occur in Chagas myocarditis. [69] In addition, mural thrombi (i.e., thrombi that formed on the endocardium) have been found in patients with Chagas disease or lymphocytic myocarditis ...

heart. The pericardium was incised longitudinally and the LAD was identified. A 7.0 silk suture was placed around the LAD for permanent blocking of arterial blood flow. For the ischemia-reperfusion model, an additional piece of 2–3 mm PE 10 tubing was placed between the suture. After 60...

for the purpose of diagnosing morphological changes (e.g.myocardial ischemia, ventricular hypertrophy), the ability to do so increases as the number of leads increases. The 12-lead ECG is a trade-off between sensitivity, specificity, and feasibility. Obviously, having 120 leads (which has been ...
Heart rate, blood pressure, and ECG results were obtained at baseline and during each stage of the protocol. Patients were questioned about any symptoms during exercise. Testing was terminated when the patients achieved their target heart rate or developed limiting symptoms, unequivocal ischemia, or ...
