OBJECTIVE: To observe the clinical efficacy of wrist-ankle acupuncture in the treatment of functional frequent premature ventricular contractions (PVCs). METHODS: A total of 64 patients with functional frequent PVCs were randomly divided into an observation group and a control group, 32 cases in each group. The observation group was treated with wrist-ankle acupuncture at bilateral upper 1 and upper 2 on the wrist. The control group received sham acupuncture at the same points as the observation group. Both groups were treated once every day from Monday to Friday, with the needles retained for 60 min each time, for a total of 4 weeks. The TCM syndrome score, the 24-hour PVC count, and MOS 36-item short form health survey (SF-36) score were compared between the two groups before and after treatment, and the clinical efficacy was evaluated after treatment. RESULTS: After treatment, the TCM syndrome scores and the 24-hour PVC counts in both groups were reduced compared with those before treatment (P<0.01), and the above indexes in the observation group were lower than those in the control group (P<0.01). After treatment，scores of all SF-36 items in the observation group were increased compared with those before treatment (P<0.01); in the control group, the scores of general health (GH), social function (SF) and role-emotional (RE) were increased compared with those before treatment (P<0.05). After treatment, scores of all SF-36 items in the observation group were higher than those in the control group (P<0.01). The total effective rate in the observation group was 90.6% (29/32), which was higher than 46.9% (15/32) in the control group (P<0.01). CONCLUSION Wrist-ankle acupuncture has a significant clinical efficacy in the treatment of functional frequent PVCs. It can effectively improve symptoms such as chest tightness and palpitations, reduce 24-hour PVC count, and improve patients' quality of life.

A case of an elderly patient with severe aortic insufficiency who carried high risks for surgical valve replacement. After a detailed preoperative evaluation, the patient successfully received transapical transcatheter aortic valve replacement. Postoperatively, complete left bundle branch block developed, resulting in impaired left ventricular function. Despite guideline-directed medical therapy for heart failure, cardiac function showed no significant recovery. At 4.5 months post-surgery, left bundle branch pacing was performed, leading to a marked improvement in cardiac function.

Background and Objective: Premature ventricular complex (PVC) burden exhibits one of three circadian types, classified as fast-type, slow-type, and independent-type PVC. It is unknown whether PVC circadian types have different heart rate variability (HRV) parameter values. Therefore, this study aimed to evaluate differences in HRV circadian rhythm among fast-, slow-, and independent-type PVC. Methods: This cross-sectional observational study consecutively recruited 65 idiopathic PVC subjects (23 fast-, 20 slow-, and 22 independent-type) as well as five control subjects. Each subject underwent a 24-hour Holter to examine PVC burden and HRV. HRV analysis included components that primarily reflect global, parasympathetic, and sympathetic activities. Repeated measures analysis of variance was used to compare differences in HRV circadian rhythm by PVC type. Results. The average PVC burden was 15.7%, 8.4%, and 13.6% in fast-, slow-, and independent-type idiopathic PVC subjects, respectively. Global, parasympathetic nervous system, and sympathetic nervous system HRV parameters were significantly lower in independenttype PVC versus fast- and slow-type PVC throughout the day and night. Furthermore, we unexpectedly found that tendency towards sympathetic activity dominance during nighttime was only in independent-type PVC. Conclusion The HRV parameters are reduced in patients with independent-type PVC compared to fast- and slowtype PVC. Future research is warranted to determine possible differences in the prognosis between the three PVC types.

The electrocardiographic analysis of heart blocks provides great opportunities for the discussion of mechanisms of electrical cardiac conduction, serving as “teachable moments” in medicine. Recognition of heart blocks can sometimes be a challenge as they can present in many forms, different severities and levels of blocks that present as varied patterns on electrocardiographic tracing. The ultimate key to correct diagnosis rests on adequate understanding of normal electrophysiology of the electrical system of the heart. While it is vital to recognize the pattern, we should always know and understand the physiology behind the pattern. This article presents a detailed analysis of a case of heart block which can easily be misinterpreted on first look. The case is featured not for its rarity but for the interesting concepts in cardiac electrophysiology that are highlighted. Navigation of the different elements of tracing can be an adventure and a great learning experience enjoyed by both students and experts.

OBJECTIVE: To investigate the clinical manifestations and laboratory indicators of anti-Sjögren's-syndrome-related antigen A (SSA) antibody associated fetal cardiac disease. METHODS: Pregnant women hospitalized at Peking University People's Hospital from January 2013 to July 2023 were included. Eleven patients with anti-SSA antibody positive were eventually diagnosed with fetal cardiac di-sease. And patients with anti-SSA antibody positive without fetal cardiac disease were selected as controls. Clinical manifestations, laboratory indications and drug usage were compared between the two groups. RESULTS: Among these 11 patients, congenital heart block was confirmed in seven, which was the most common manifestations of fetal cardiac malformation. The proportion of the patients diagnosed with autoimmune disease before pregnancy in fetal cardiac malformation group was significantly lower than that in the control group (P=0.032), while most of the patients in the fetal cardiac malformation group received immune-related examinations for the first time because of this time's fetal cardiac diagnosis. While most of the patients in the control group received routine examinations because of autoimmune diseases diagnosed before pregnancy. During pregnancy, the white blood cell level [(9.29±2.58)×10⁹/L vs. (7.10±1.90×10⁹/L, t=3.052, P=0.004], erythrocyte sedimentation rate [(49.50 (48.00, 51.00) mm/h vs. 23.00 (15.00, 30.25) mm/h, Z=-2.251, P=0.024], IgA level [3.46 (2.30, 5.06) g/L vs. 2.13 (1.77, 2.77) g/L, Z=-2.181, P=0.029], and antinuclear antibody (ANA) titers [1∶320 (1∶160, 1∶320) vs. 1∶80 (1∶40, 1∶160), Z=-3.022, P=0.003] were significantly higher in fetal cardiac malformation group than in the control group. The proportion of positive anti-SSB antibody during pregnancy did not show a statistically significant difference between the two groups (37.5% vs. 7.7%, P=0.053). There was no significant difference in hydroxychloroquine dosage and initiation time between the two groups. The dosage of prednisone in the second and third trimesters was significantly higher in the cardiac malformation group than that in the control group, but there was no significant difference in the first trimester. CONCLUSION Fetal cardiac disease is rare in pregnant women with anti-SSA antibody. White blood cell, erythrocyte sedimentation rate, IgA, the titer of ANA positivity were higher in the fetal heart disease group during pregnancy. Since congenital heart block is difficult to reverse, its prevention and monitoring are more important than remedial treatment.
