The company said the RhythmAnalytics platform uses an enhanced deep-learning technique to detect over 15 types of cardiac arrhythmias along with beat-by-beat morphology computation which include ventricular arrhythmias, ventricular ectopic beats and all non-paced arrhythmias including Atrial Fibrillation (AFib).
Electrocardiogram (ECG) revealed deep T-wave inversions in leads V2 to V4, with ventricular ectopic beats (Figure 2).
There are two main sources of possible errors in ARH detection/classification: outliers and ectopic beats. The ECG signals are usually filtered by hardware methods and the basic notch filter for 50 Hz frequency is used to remove the power line interference.
Frequent premature ventricular contractions 12(11.2%) and atrial ectopic beats 9(8.4%) were the most common findings.
Clinically, supraventricular ectopic beats (SVEB) and ventricular ectopic beats (VEB) are two critically abnormal and serious heartbeats, and the performance of the classifiers also was elevated by testing S and V heartbeat classification [9, 10, 15].
24 hour ECG Holter monitoring has shown stable sinus rhythm with an average of 67 beats per minute (minimum of 60 beats per minute and maximum 87 beats per minute), diffuse variable ST segment depressions and negative T waves, rare and isolated supraventricular and ventricular ectopic beats, with uniform distribution between active and passive periods.
(3) Specific arrhythmias included atrial fibrillation, atrial flutter, supraventricular tachycardia, ventricular tachycardia, sinus bradycardia, ectopic beats, and sudden cardiac death.
rapid regular, rapid irregular, slow regular, slow irregular, ectopic beats, missed beats or strong beats.
Comment: Magnesium deficiency can lead to various arrhythmias, including ventricular premature beats, atrial fibrillation, supraventricular tachycardia, torsades de pointes, supraventricular ectopic beats, bigeminal rhythm, and ventricular fibrillation.
Ectopic beats can occur in a heart that is otherwise functioning normally and causes no symptoms.
