“…While the scar in ischemic cardiomyopathy is usually sub-endocardial, patients with non-ischemic cardiomyopathy (NICM) often have patchy VT circuits located in mid-myocardium and epicardial location ( 3 , 4 ). Patients with non-endocardial scars may require epicardial access, bipolar ablation, and more advanced ablation techniques ( 5 ). Patients with NICM, who have failed prior endocardial ablations, often have more extensive scar in the epicardium with more than 50% of these patients requiring an epicardial ablation ( 6 , 7 ).…”

Catheter ablation of ventricular arrhythmias has evolved considerably since it was first described more than 3 decades ago. Advancements in understanding the underlying substrate, utilizing pre-procedural imaging, and evolving ablation techniques have improved the outcomes of catheter ablation. Ensuring safety and efficacy during catheter ablation requires adequate planning, including analysis of the 12 lead ECG and appropriate pre-procedural imaging. Defining the underlying arrhythmogenic substrate and disease eitology allow for the developed of tailored ablation strategies, especially for patients with non-ischemic cardiomyopathies. During ablation, the type of anesthesia can affect VT induction, the quality of the electro-anatomic map, and the stability of the catheter during ablation. For high risk patients, appropriate selection of hemodynamic support can increase the success of VT ablation. For patients in whom VT is hemodynamically unstable or difficult to induce, substrate modification strategies can aid in safe and successful ablation. Recently, there has been an several advancements in substrate mapping strategies that can be used to identify and differentiate local late potentials. The incorporation of high-definition mapping and contact-sense technologies have both had incremental benefits on the success of ablation procedures. It is crucial to harness newer technology and ablation strategies with the highest level of peri-procedural safety to achieve optimal long-term outcomes in patients undergoing VT ablation.

Number of coronary artery disease cases and ventricular arrhythmias has been increasing in India. One of the common forms of cardiac disorder is Ventricular Tachycardia(VT). Due to improper electrical activities in the ventricles, consistent and rapid heart rate occurs, which produces Ventricular Tachycardia disorder. Short time period may not lead to severe heart problem, but the longer duration increases it may be a severe heart issue. In this disorder,for short durations it is possible that there may not be any symptoms or few symptoms with palpitations(increase / decrease in heart beats), dizziness or pain in chest. This disorder may result in cardiac arrest. This may also results into ventricular fibrillation. initially it was found that near about 7% of people in cardiac arrest are caused by Ventricular Tachycardia. In this work, a novel platform for real time diagnosis of Ventricular Tachyarrhythmia with the help of a portable Single lead ECG device is proposed. The gateway for signal analysis and combined edge and cloud based processing for the diagnosis is used. The biosignal captured by the device in LEAD II configuration is pushed to a cloud based diagnosis API through a mobile gateway. An algorithm in the cloud analyses this signal and finds out P, Q, R, S, T, their amplitude positions, onset and offset. From the onset and offset ST segment slope, elevation, depression, S morphology and ST segment variation statistics is captured and classified using rule based classifier. The work evaluates the performance of the classifier with Physionet dataset. The accuracy of the system was found to be 90% with accuracy of detecting normal ECG being 100% where as the accuracy of detection of VT being 80%. Results shows that the system is extremely efficient in detecting Ventricular Tachyarrhythmia and many related cardio vascular diseases.
