Each wave or segment of ECG corresponds to certain events of the cardiac electrical cycle among which QRS complex is essential to detect the heartbeat. In this paper, we propose an ECG beat detection algorithm using signal processing. The detection algorithm is based on S-G noise filter and ...
where \(W_1\) depends on the duration of the QRS complex, and \(W_2\) depends on the heartbeat duration. The mean (\(\mu \)), of the enhanced signal is calculated and multiplied by a factor (\(\beta \)) whose optimum value was chosen by hit and trial method. The output numb...
For instance, patients with CHD often display right atrial dilation, elevated right ventricular volume and pressure, low systemic ventricular contractility and a prolonged QRS complex duration.48,58,59 These pathophysiologies or surgically induced impairments are connected to the worsening of ANS ...
In the recently completed COMPANION trial, cardiac resynchronization therapy (pacing both the left ventricle as well as the right ventricle) has been shown to improve mortality in individuals with NYHA class III or IV heart failure with a widened QRS complex onEKG.2 Delaying the progression of he...
Heart failure (HF) refers to a complex condition resulting from the structural and/or functional inability of the heart to supply a normal cardiac output to meet metabolic needs. In HF, impaired ventricular filling or ejection of blood leads to fatigue , dyspnea , and fluid retention or edema...
(CSP). The Strauss criterion is, QRS duration ≥ 140 ms for men or 130 ms for women; QS or rS complex in leads V1and V2; and mid-QRS notching or slurring in ≥ 2 of the following leads: V1, V2, V5, V6, I, and ...
Heartbeat segmentation methods (i.e., detection of the R peak or the QRS complex) have been studied for more than three decades [49], [53], [46], [54], [55] and the generations of these algorithms and newly developing methods reflect the evolution of the processing power of computers...

Heart diseases are leading to death across the globe. Exact detection and treatment for heart disease in its early stages could potentially save lives. Electrocardiogram (ECG) is one of the tests that take measures of heartbeat fluctuations. The deviatio
