How is ventricular tachycardia diagnosed on ECG?
If the QRS complex in V1–V2 resembles a left bundle branch block (i.e negative QRS)
- The initial portion of the QRS complex is smooth in ventricular tachycardia.
- R-wave duration ≥40 ms suggest ventricular tachycardia.
- Duration from start of QRS complex to nadir of S-wave ≥60 ms suggests ventricular tachycardia.
What is PhysioNet database?
The PhysioNet resource has three closely interdependent components: An extensive archive (“PhysioBank”) of well-characterized digital recordings of physiologic signals, time series, and related data for use by the biomedical research community. PhysioNet also includes clinical and imaging data related to critical care.
How can a PhysioNet obtain data?
Use the physiobank ATM. Under ‘Input’ select your database and record. Under ‘Output/length’ select ‘to end’. Under ‘Toolbox’ select ‘Export signals at .
What is MIT BIH database?
Abstract. The MIT-BIH arrhythmia database is publicly available dataset which provides standard investigation material for the detection of heart arrhythmia. Since 1980, it is used for purpose of fundamental research and medical device development on cardiac rhythm and related diseases.
What is PhysioBank?
PhysioBank is a large and growing archive of well-characterized digital recordings of physiologic signals and related data for use by the biomedical research community. Follow the links from the PhysioBank Archives for details about the databases and for access to the data files.
What is the purpose of PhysioNet?
PhysioNet Works provides reliable and secure web-accessible backup, tools for viewing and annotating your data interactively, and an active community of researchers around the world who can help you by annotating, analyzing, and reviewing your data, and perhaps by contributing additional relevant data.
How serious is ventricular tachycardia?
The ventricles (lower chambers of the heart) are where ventricular tachycardia starts. It is a serious condition because it can lead to ventricular fibrillation, whereby the heart no longer pumps blood, leading to sudden death.
What medications cause ventricular tachycardia?
Medications. Certain drugs can cause your heart to beat faster. Drugs that extend QT interval such as class III antiarrhythmics and levofloxacin can cause ventricular tachycardia. Other drugs such as halothane that decrease the conduction velocity may also cause your heart to beat faster.
How can ventricular tachycardia be diagnosed?
The most common test used to diagnose ventricular tachycardia is an electrocardiogram (ECG/EKG). An EKG records your heart’s electrical activity. Electrodes (small sticky patches) are placed on your chest and arms to record the heart’s rhythm, and the pattern prints on graph paper.
Can ventricular tachycardia resolve itself?
In brief: SVT. Typically, SVT will not go away on its own. Think of it like a stray wire that short-circuits the electricity. Until the stray wire is cut or removed, the short-circuits will continue. Stranger things have happened in medicine, but the general consensus is going to be no, it won’t go away on its own.
