Far field r wave oversensing
WebFeb 1, 2012 · Far-field R-wave sensing may cause the erroneous detection of AT/AF and inappropriate AMS, yielding inaccurate diagnostic information, such as AHRE, AF burden and numbers of AMS; it may also cause pacemaker syndrome due to AV dyssynchrony or development of new AF. WebA device senses cardioelectrical signals using a right atrial (RA) lead, which might include far-field R-waves as well as near-field P-waves. The device concurrently senses events …
Far field r wave oversensing
Did you know?
WebA device senses cardioelectrical signals using a right atrial (RA) lead, which might include far-field R-waves as well as near-field P-waves. The device concurrently senses events using a proximal electrode of an LV lead, which can sense both P-waves and R-waves as substantially near-field events. WebFar-field R wave (FFRW) oversensing in atrial channel is known to cause inappropriate automatic mode switch. We describe a case of 63-year-old lady with dual-chamber permanent pacemaker implanted 2 years back for symptomatic infra-hisian complete heart block and normal biventricular function.
