  • occur
  • If the patient is deemed to be pacemaker dependent, it is important to establish a secondary method for pacing the patient should a pacemaker failure occur. (apsf.org)
  • Implant failure can occur due to the degradation of the material an implant is made of. (wikipedia.org)
  • Implant failure due to bacterial infection of the implant can occur at any point of implant lifetime. (wikipedia.org)
  • Ectopic pacemakers can occur within healthy hearts in response to various stimulating events, such as: Increased local parasympathetic nervous system activity Elevated sympathetic nervous system output Overstimulation from drugs such as caffeine, digitalis and catecholamines. (wikipedia.org)
  • Chest pain, including angina, does not typically occur due to heart failure. (wikipedia.org)
  • High-output heart failure can occur when there is an increased cardiac output. (wikipedia.org)
  • Cardiovascular
  • Pace Medical and distributed in the UK by APC Cardiovascular) Do not use these pacemakers with epicardial pacing wires until they have undergone 3 upgrades. (www.gov.uk)
  • symptomatic
  • Whereas the discordance rate between the reported symptomatic response to CRT and parameters of systolic function has consistently been high, there is excellent concordance between the symptomatic response to pacemaker therapy and objective measures of diastolic function. (onlinejacc.org)
  • Pacemakers are devices placed for bradyarrhythmias, and they remain the only effective treatment for ameliorating symptomatic bradycardia due to sinus node dysfunction (e.g., sick sinus syndrome) or a failure of impulse propagation (e.g., complete heart block). (apsf.org)
  • rhythm
  • In some cases, you may get a pacemaker that is combined with a device to shock your heartbeat back to a normal rhythm if it is dangerously fast. (lancastergeneralhealth.org)
  • Pacemaker rhythm in VVI mode at 90 bpm. (proz.com)
  • It is important to establish if the patient is pacemaker dependent, which is defined as the absence of a perfusing rhythm without pacing. (apsf.org)
  • However, in the instance of either a malfunctioning SA node or an ectopic focus bearing an intrinsic rate superior to SA node rate, ectopic pacemaker activity may take over the natural heart rhythm. (wikipedia.org)
  • This phenomenon (an intrinsically slower pacemaker activity being unmasked by failure of faster pacemaker tissue 'upstream') is called an escape rhythm, the lower rhythm having escaped from the dominance of the upper rhythm. (wikipedia.org)
  • Location of the pacemaker can also change its effect on the SA node and its rhythm. (wikipedia.org)
  • stroke volume
  • Pacemaker-induced change in loading conditions (an increase in the AVI from 130 to 200 ms) can have a major effect on diastolic function (alteration of LV inflow pattern from restrictive to pseudonormal ), without any demonstrable improvement in stroke volume. (onlinejacc.org)
  • include
  • These include MRI machines (unless your pacemaker is safe for an MRI), battery-powered cordless power tools, and CB or ham radios. (lancastergeneralhealth.org)
  • Typical failure mechanisms include tissue damage and implant detachment due to bacteria generated biofilm. (wikipedia.org)
  • Common types of medications that are prescribed for heart failure patients include ACE inhibitors, vasodilators, beta blockers, aspirin, calcium channel blockers, and cholesterol lowering medications such as statins. (wikipedia.org)
  • optimal
  • According to a review in 2009, there is apparently no evidence of benefit of fluid restriction in patients with clinically stable heart failure otherwise receiving optimal pharmacological treatment. (wikipedia.org)
  • adverse
  • Report all adverse incidents involving these pacemakers to the MHRA's Adverse Incident Centre and the manufacturer. (www.gov.uk)
  • atrial fibrillation
  • The patient has AF (atrial fibrillation, as well said Alvaro) and has a pacemaker implanted, which is programmed in VVI mode (meaning it can only sense and pace the right ventricle). (proz.com)
