dual chamber pacemaker A pacemaker with pacing electrodes in both the right atrium and the right ventricle, which helps maintain the physiological relationship between atrial and ventricular contraction, and allows the paced heart to follow the increase in sinus rate which occurs during exercise.
Dual-site atrial pacing better than HRA by echo and Doppler The DAPPAF investigators examined the echocardiographic and Doppler effects of HRA, dual-site atrial pacing, and single site pacing, all in the DDDR pacing mode, on atrial and ventricular function in 81 of the study's patients.
Driving . The patient must inform the Driver and Vehicle Licensing Agency (DVLA) that they have a pacemaker. For an ordinary driving licence. The patient can start driving again after one week as long as: There are no symptoms such as dizziness or fainting which may affect driving. The patient attends regular check-ups in the pacemaker clinic.
Unipolar systems (ventricular) are used in cases where atrioventricular (AV) conduction is likely to return. When there is normal AV conduction and a sinoatrial (SA) disorder then the pacing wire is situated in the right atrium. Dual-chamber pacemakers. Have pacing electrodes in both the right atrium and the right ventricle.
