All pacemaker-dependent pts (based on the presence of ventricular paced rhythm on the electrocardiogram; EKG) without atrial organized activity were chosen (absence of sinus node P waves) to verify the anticoagulation status. We then verified if the physician in charge was notified of the presence...

1.A method for use with an implantable cardiac rhythm management device, the method comprising:delivering ventricular pacing pulses to a selected ventricular chamber using the device;detecting depolarization events within the other ventricular chamber;distinguishing depolarization events in the other ventricula...
For arrhythmia detection, the device100utilizes the atrial and ventricular sensing circuits,244and246, to sense cardiac signals to determine whether a rhythm is physiologic or pathologic. In reference to arrhythmias, as used herein, “sensing” is reserved for the noting of an electrical signal or...
of cardiac MRI can provide valuable information about the underlying substrate. Mapping of the VT circuit with multipolar catheters and improved detection of slow conduction zones in sinus rhythm have reduced procedural time, decreased the need to map in VT, and facilitated improved procedural success...
She returned to sinus rhythm, but one minute later had another Spike-on-T event initiating PMVT. She was successfully defibrillated with 360J. Post-shock EKG showed an asynchronous Bi-V paced rhythm at 50 bpm. Decision Making: The patient was admitted to the CCU for post-resuscitation ...
Paced rhythmSgarbossa criteriaVentricular pacemakerScreening for acute myocardial infarction (AMI) in patients with ventricular pacemakers (VP) is a diagnostic challenge. We report a case where application of the Modified Sgarbossa criteria (mSC) would have immediately identified AMI in a patient with...
(CRT), or various combinations of such devices. Such devices can typically sense intrinsic heart contractions, deliver pacing pulses to evoke responsive heart contractions, or deliver a shock to interrupt certain arrhythmias. This can help improve the patient's heart rhythm or can help coordinate a...
