Introduction:Cardiac rhythm by ECG can be different from cardiac rhythm visualized by echocardiography (echo). Cardiac arrest interventions are largely based on the ECG rhythm and some patients with ventricular fibrillation (vfib) demonstrating a non-shockable ECG may not be rapidly defibrillated.#...
Deep brain stimulation devices can disrupt cardiac rhythm interpretation by causing electrocardiogram artifact. We report the case of a deep brain stimulating device initiating ventricular fibrillation simulated electrocardiogram artifact in the prehospital setting. Mimicked ventricular fibrillation due to a deep...
Arrhythmia Recognition: The Art of Interpretation, 2nd Edition (online access included) Ectopic ventricular rhythms, such as extra systoles, tachycardia, flutter and fibrillation may also be encountered in the advanced stages of hyperkalemia Ventricular arrhythmias presage terminal ventricular standstill. Fat...
ECG interpretation using this approach has been shown to predict low LV ejection fraction (≤ 35%) [30], atrial fibrillation [31], hypertrophic cardiomyopathy [32] and myocardial infarction [33]. Utilizing AI tools to guide clinicians in ECG interpretation can improve patient care by increasing...
Ventricular fibrillation, asystole and sudden cardiac death can occur soon after ventricular tachycardia if action is not taken immediately. Ventricular tachycardia can occur with many variations of the QRS morphology, depending on where the arrhythmia originates, which sometimes makes diagno...
MI, myocardial infarction; LADO, occlusion of the left anterior descending branch; LDTN, left dorsal branch of the thoracic nerve; VAs, ventricular arrhythmias; VPB, ventricular premature beat; VT, ventricular tachycardia; VF, ventricular fibrillation Full size image LDTN Stimulation The LDTN at the...
Ischemic heart disease:myocardial infarctionin the acute phase (monomorphic or polymorphic ventricular tachycardia,with the risk of transforming into ventricular fibrillation) or in chronic phase (monomorphic ventricular tachycardia); Cardiomyopathy: primitive (dilated, hypertrophic) or secondary (hypertension,mi...
We have previously shown that a neural network can be trained to identify subtle and nonspecific patterns in a standard ECG to identify the presence of occult cardiovascular disease including LV dysfunction, intermittent atrial fibrillation, and hypertrophic cardiomyopathy.9,10 The fact that the coronavi...
We propose the analysis of the ECG signal for the real-time detection of the onset of ventricular fibrillation using a time-frequency method [7,54]. Reduction of network interference and other noises, which correspond to high frequency noises in these signals was carried out. After performing th...
The causes of ventricular fibrillation (VF) are not yet elucidated, and it has been proposed that different mechanisms might exist. Moreover, conventional analysis methods do not seem to provide time or frequency domain features that allow for recognition of different VF patterns in electrode-recorde...
