Problems solved by technology

This is an excellent conversion tool; however, unless the underlying cause of AF is addressed, it is likely to recur
Implantable cardioverter-defibrillators (ICDs) have been used for the conversion of AF; however, because the patient is conscious when the shock is delivered, many individuals find the discomfort of the shock intolerable

Embodiment approach

[0085] exist Figure 5 In , treatment with an AED is shown. The AED device 90 is an external defibrillator that checks the rhythm of the heart and can deliver an electrical shock to restore the normal rhythm. The device 90 has written instructions and gives spoken instructions to the operator 94 . The operator 94 will place the electrode patches or plates 96 on the chest area 98 of the patient 100 so that they adhere well and conduct electricity to the chest area 98 . Consistent with embodiments of the present invention, electrode patches or plates 96 would be configured with circuitry to apply a rotational current (not shown) prior to delivering a defibrillation shock.

[0086] Figures 6A-6C shows an example of a typical amplifier-generated shock waveform with a rising ramp at a constant voltage ( Figure 6A ), constant current ( Figure 6B ) and constant energy ( Figure 6C ) indicates the operating mode. Impedance, voltage and current delivered in the examples are s...

Abstract

A method and apparatus for treating a cardiac condition in a human or animal patient comprises contacting an area of skin spanning the chest area of the patient with at least two patches or electrode paddles that apply low voltages and currents in a rotational manner to pre- stimulate that area, followed by applying a high voltage shock in rapid succession through the patient's heart through at least two electrode pad patches or paddles, wherein an amplifier-based external defibrillation cardioversion system is used. Also, an external pacing system is employed using ascending ramp or any arbitrary ascending or level waveform for transcutaneous pacing which employ a constant current delivery mode. Treatable conditions include atrial fibrillation (AF), atrial tachycardia (AT), ventricular fibrillation (VF), and ventricular tachycardia (VT).

Description

[0001] Cross References to Related Applications [0002] This patent is based on, and claims the benefit of its filing date, co-pending, commonly assigned US Provisional Patent Application Serial No. 62 / 062,331, filed October 10, 2014, which is incorporated herein in its entirety. [0003] field of invention [0004] The present invention relates to the electrical management of cardiac arrhythmias or abnormal cardiac rhythms occurring in the electrical system of the atrial or ventricular chambers of the human heart. More particularly, the present invention relates to the treatment of ventricular fibrillation, ventricular tachycardia, atrial fibrillation or atrial tachycardia by external defibrillation and / or cardioversion. [0005] Background of the invention [0006] Ventricular fibrillation (VF) is a cause of cardiac arrest and sudden cardiac death. During VF, the ventricular muscle contracts in a much less organized pattern than during normal sinus rhythm, so the ventricle...
