Clinical Trial Randomized Controlled Trial Review
A review is presented at the main causes of the change in paradigm that has occurred in the past 10 years in antiarrhythmic pharmacotherapy. The new attitude is ascribed to (1) the advances made in the application of non-pharmacological therapeutic modalities (radiofrequency catheter ablation, implantable antiarrhythmic devices), (2) the modification of therapeutic practice in response to the results of large-scale prospective randomized clinical trials, and (3) the proper recognition and appropriate appreciation of the frequently life-threatening proarrhythmic action of antiarrhythmic drugs. The current state of knowledge is discussed as concerns the anti- and proarrhythmic effects of the drugs available at present, and also their safe clinical use.

Review
Cardiac arrhythmias, with, on top of the list, atrial fibrillation, are frequent conditions and any physician might have to get involved at any stage of patient care (from diagnosis to treatment), without always having the opportunity to immediately refer to the cardiologist. The aim of this review is to present a summary of pathophysiology, clinical and electrocardiographic presentations, as well as diagnostic and therapeutic strategies for the main cardiac arrhythmias. Supra-ventricular tachycardias (atrial fibrillation and flutter, atrioventricular reciprocating tachycardias) and ventricular tachycardias will be consecutively presented and discussed.

Review
Proarrhythmia is defined as the aggravation of an existing arrhythmia or the development of a new arrhythmia secondary to antiarrhythmic drug. Proarrhythmic events include drug-induced bradyarrhythmias, atrial and ventricular proarrhythmias. New onset sustained or incessant ventricular tachycardia and torsade de pointes can be life threatening. This article reviews the incidence, aggravating factors, and treatment of proarrhythmia.

Review
Evaluation of patients with ventricular arrhythmia (VA) is a frequently encountered problem in clinical practice. Determining which patients require treatment and which are at risk for sudden cardiac death remains challenging, however. Classification of VAs as significant, prognostically important, having unknown importance, or insignificant will help determine whether treatment is warranted and beneficial. Tests for evaluating suspected VA, including ambulatory electrocardiographic monitoring, exercise testing, and electrophysiologic studies, are used to determine the presence or frequency of an arrhythmia, correlate the arrhythmia with symptoms, determine a prognosis, or evaluate the efficacy of drug therapy.

Electrocardiograms (ECGs) are widely used for diagnosing cardiac arrhythmia based on the deformation of signal shapes due to changes in various heart diseases. However, these abnormal signs may not be observed in some 12 ECG channels, depending on the location, the heart shape, and the type of cardiac arrhythmia. Therefore, it is necessary to closely and comprehensively observe ECG records acquired from 12 channel electrodes to diagnose cardiac arrhythmias accurately. In this study, we proposed a clustering algorithm that can classify persistent cardiac arrhythmia as well as episodic cardiac arrhythmias using the standard 12-lead ECG records and the 2D CNN model using the time-frequency feature maps to classify the eight types of arrhythmias and normal sinus rhythm. The standard 12-lead ECG records were provided by China Physiological Signal Challenge 2018 and consisted of 6877 patients. The proposed algorithm showed high performance in classifying persistent cardiac arrhythmias; however, its accuracy was somewhat low in classifying episodic arrhythmias. If our proposed model is trained and verified using more clinical data, we believe it can be used as an auxiliary device for diagnosing cardiac arrhythmias.

Comparative Study Review
The inherited short QT syndrome (SQTS) is a novel, genetically determined arrhythmia that resembles the pathophysiological counterpart of congenital long QT syndrome (LQTS). Gain-of-function ion channel mutations in cardiac potassium channel genes are the currently known cause of SQTS and obvious genetic heterogeneity is evident from the few reported families. At present, three subforms are known, and probably, specific T-wave patterns make each subform recognizable. So far, only a few cases have been genetically unraveled. Treatment includes ICD implantation as the first-line option due to a high occurrence rate of ventricular fibrillation and repolarization-prolonging medications such as quinidine are under investigation. Whenever atrial and/or ventricular fibrillation occur in an idiopathic setting, SQTS has to be considered a potential cause.
