What is Dddr mode?

Dual-chamber rate-modulated (DDDR) pacing is a mode that is programmed into a pacemaker and recommended for patients with atrioventricular block and sinus node dysfunction. DDDR modes include pacing and sensing capabilities in both the ventricles and atria: Dual response to detection (triggering and inhibition)

What are VHR episodes?

Design: Clinical data and device-interrogation data were retrospectively gathered from the medical records of 220 patients treated with CRT-P. Ventricular high-rate (VHR) episodes were defined as a ventricular rate ≥ 180 beats per minute.

What does the code DDD mean?

DDD is an acronym for Discagem Direta à Distância or direct distance dialing. DDD are mandatory codes or prefixes used to call long distances in Brazil. This post is for you learn the prefixes to make national calls inside Brazil.

What does DDD mean in an ICD?

[Implantation of a dual chamber pacemaker-defibrillator (DDD-ICD) in a patient with hypertrophic obstructive cardiomyopathy]

What does Dddr stand for?


Acronym Definition
DDDR Dual Chamber Rate Adaptive Pacemaker
DDDR Port D Data Direction Register (computing)

Can you feel V-tach?

Signs and symptoms that occur during an episode of ventricular tachycardia are due to a lack of oxygen and may include: Chest pain (angina) Dizziness. Pounding heartbeat (palpitations)

What is a NSVT episode?

NSVT is defined as an episode of ventricular tachycardia that:2. Involves a heart rate of more than 100 beats per minute. Persists for at least three heartbeats. Lasts less than 30 seconds.

Is a DDD pacemaker an ICD?

Is Dddr pacemaker and defibrillator?

DDDR = dual chamber rate adaptive pacemaker; EPS = electrophysiology study; ICD = implantable cardiovertor defibrillator; LVEF = left ventricular ejection fraction; VF = ventricular fibrillation; VT = ventricular tachycardia; VVI = single chamber ventricular pacemaker.

Is DDI a tracking mode?

The DDI mode provides dual-chamber, sequential AV pacing with atrial sensing but no tracking of the sensed atria. AV synchrony is only provided at the current atrial pacing rate (base rate pacing, rate responsive pacing or rate-smoothed pacing).

Is V-tach life-threatening?

Ventricular tachycardia episodes may be brief and last only a couple of seconds without causing harm. But episodes lasting more than a few seconds (sustained V-tach ) can be life-threatening. Sometimes ventricular tachycardia can cause the heart to stop (sudden cardiac arrest).

Can stress cause non sustained ventricular tachycardia?

Emotional stressors can lead to ventricular ectopic beats and ventricular tachycardia. Though disturbances of cardiac rhythm due to emotional stress are often transient, sometimes the consequences can be seriously damaging and even fatal [11].

What is the DDD method?

Domain-Driven Design(DDD) is a collection of principles and patterns that help developers craft elegant object systems. Properly applied it can lead to software abstractions called domain models. These models encapsulate complex business logic, closing the gap between business reality and code.
