Background:
CardioInsight™ is a noninvasive three-dimensional mapping system technology which offers a unique method for arrhythmia characterization and localization. With a 252-lead ECG vest on the patient's torso and a noncontrast CT scan, epicardial potentials are detected and by means of reconstruction algorithms activation and phase maps are created, offering a deeper understanding of localization and mechanisms of arrhythmias including atrial fibrillation without the need for an endocardial catheter.
Materials And Methods:
The system has proven to be accurate and applicable in the clinical setting of accessory pathways, premature ventricular contractions (PVC), atrial tachycardias and atrial fibrillation. Beat-to-beat analysis offers detection and thus a therapeutic approach for arrhythmias which occur only paroxysmally such as supraventricular extrasystoles, atrial bursts or PVCs. Another advantage is the simultaneous display of various heart chambers such as the left and right atrium. However, major multicenter prospective randomized data are still lacking.
Conclusion:
If in the future noninvasive mapping could be achieved with MRI and if the technology was compatible with invasive mapping systems so that catheter positioning and noninvasive maps can be merged, the authors believe that this would represent a new dimension of mapping technology and ablation strategy of arrhythmias.

Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....
Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
