Sustained ventricular tachycardia is a rhythm greater than 100 bpm usually lasting more 30 seconds. It manifests with broad QRS tachyarrhythmia which has similar configuration. This happens from one beat to another, showing chain of depolarization for every beat. Ventricular its origin stable focus. However, in conditions like structural cardiac disease, the substrate place that patchy replacem...

The Electrocardiogram (ECG) plays significant role in assessing patients with abnormal activity in their heart. ECG recordings of the patient taken to analyze abnormality and classify type of disorder present in the heart functionality. An Electrocardiogram is a bioelectrical signal that records the heart’s electrical activity versus time. It is used to measure the rate and regularity of heartb...

Background: Telmisartan and irbesartan, two of the main AT1 receptor antagonists available for the control of cardiovascular diseases, differ in their pharmacological properties, including time of dissociation from the AT1 receptor and the ability to activate other receptors, with potential impact on their relative clinical efficacy. Objectives: The aim of this study was to compare the acute ca...

The heartbeat arises rhythmically in the sino-atrial node (SAN) and then spreads regularly throughout the heart. The molecular mechanism underlying SAN rhythm has been attributed by recent studies to the interplay between two clocks, one involving the hyperpolarization activated cation current If (the membrane clock), and the second attributable to activation of the electrogenic NaCa exchanger ...

Studies on heart rate variability (HRV) have become popular and the possibility of diagnosis based on non-invasive techniques compels us to overcome the difficulties originated on the environmental changes that can affect the signal. We perform a non-parametric segmentation which consists of locating the points where the signal can be split into stationary segments. By finding stationary segmen...

This paper proposes a novel system to classify three types of electrocardiogram beats, namely normal beats and two manifestations of heart arrhythmia. This system includes three main modules: a feature extract ion module, a classifier module, and an optimization module. In the feature ext raction module, a proper set combining the shape features and timing features is proposed as the efficient ...

In this paper we have utilized a hybrid lightweight 1D deep learning model that combines convolutional neural network (CNN) and long short-term memory (LSTM) methods for accurate, fast, automated beat-wise ECG classification. The CNN LSTM models were designed separately to compare with the CNN-LSTM in terms of accuracy, number parameters, time required system provides an feature extraction clas...

Ventricular bigeminy refers to the appearance of paired different ventricular complexes in the body-surface ECG (Figure, A inset, lead V2). From this ECG morphology, it has been inferred that bigeminy is generated by interaction between an extrasystolic beat and a regular periodic ventricular beat.1 The regular beat is typically generated by sinus rhythm but could also be a paced rhythm. The me...

Inevitably, reading is one of the requirements to be undergone. To improve the performance and quality, someone needs to have something new every day. It will suggest you to have more inspirations, then. However, the needs of inspirations will make you searching for some sources. Even from the other people experience, internet, and many books. Books and internet are the recommended media to hel...
