Patients with sinus bradycardia undergoing cardiac autonomic ganglion ablation.
Specific anatomic ablation of the 4 major left atrial GP and aorta-superior vena cava (Ao-SVC) GP was performed.
Briefly, catheter ablation was performed under the guidance of an electroanatomic mapping system (CARTO,BiosenseWebster,DiamondBar,California).
After completed the electroanatomic mapping of the left atrium was complete and pulmonary vein (PV) ostia identified, presumed GP clusters were ablated 1 to 2cm outside the PV-left atrium junctions at the following sites: the left superolateral area (leftsuperior GP[LSGP]), the leftinfer oposterior area(left inferior GP[LIGP]), the right superoanterior area (rightanterior GP[RAGP]), the right inferoposterior area(right inferior GP[RIGP]), and the Ao-SVC fat pad (Ao-SVCGP), and in that sequence.

활성 비교기: Pacemaker
|
Patients with sinus bradycardia received pacemaker implantation.
The patient lay flat on the bed, puncture the subclavian vein and insert two guide wires.
Cut the skin under the guide wire to make a skin bag, and stop bleeding accurately to avoid continuous bleeding of the skin bag.
The pacemaker electrode is inserted into the heart cavity by guiding the guide wire, one is placed in the ventricle and the other in the atrium, and the corresponding parameters of the electrode, such as pacing threshold, impedance, etc., are measured at the same time.
If the parameters are good, fix the electrode, connect the electrode with the pacemaker, place the pacemaker in the skin bag, fix the pacemaker and electrode, suture the skin layer by layer, and the operation is completed.

Symptom score after operation
기간: 48 months
|
Each patient subjectively assessed his or her SB-related symptom, including dizziness, fatigue, and palpitation, on a score of 1 to 10 points (mildtosevere).
The total SB-related symptom score for each patient was calculated as the sum of all scores for individual symptoms.

Quality of life score

The Medical Outcomes Study Short-Form 36 Health Survey (SF-36) was used to assess quality of life (QoL) at baseline and 12 months after ablation.
The self-administration mode was strictly followed for QoL surveys.
TheSF-36 assesses 8 specific QoL domains, namely physical functioning, role limitations due to physical health, bodily pain, general health, vitality, social functioning, role limitations due to emotional problem, and mental health.
For each subscale, scores were transformed to a scale ranging from 0 to 100, with lower scores representing a lower QoL.

Psychological quality score

The Zung Self-Rating Depression Scale is a short self administered survey to quantify the depressed status of a patient. There are 20 items on the scale that rate the four common characteristics of depression: the pervasive effect, the physiological equivalents, other disturbances, and psychomotor activities. There are ten positively worded and ten negatively worded questions. Each question is scored on a scale of 1-4 (a little of the time, some of the time, good part of the time, most of the time). |
