概括

一个冠状动脉的中心环状断层和异常的大动脉起源可以导致心室失常. 当压力测试显示没有缺血时,考虑在心律失常时进行心肌环状断路.

科学领域:

心脏病学心脏病学
心脏电生理学心脏电生理学
遗传性心脏病是一种先天性心脏病.

背景情况:

中心环状断裂 (MAD) 和冠状动脉异常大动脉起源 (AAOCA) 与心室失律 (VA) 有关.
关于MAD和AAOCA的同时发生及其对VA的综合影响的数据有限.
了解这种关联对于诊断和管理复杂的心脏疾病至关重要.

研究的目的:

为了调查AAOCA和MAD在患有心室心律失常的患者中同时发生的情况.
突出MAD作为潜在的节律失常基质的临床意义,特别是当缺血症被排除在外时.

主要方法:

两名确诊AAOCA和MAD的患者的病例报告介绍.
临床评估包括电生理学研究和成像方法.
对MAD,AAOCA和心室节律失常的现有文献的综述.

主要成果:

两位被介绍的患者都表现出心室心律不整.
鉴于AAOCA和MAD的同时出现,这被认为是导致它们心律失常的潜在因素.
诊断工作排除了显著的缺血性心脏病作为主要原因.

结论:

mitra环状断路应被认为是心室心律失常的重要潜在原因.
在无法解释的腹腔失常的情况下,特别是当压力测试没有显示缺血时,建议对MAD进行评估.
AAOCA和MAD的组合可能代表一种特定的表型,使其易患心室失常症.

Cardiovascular System Abnormal Findings II: Auscultation

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Imbalances in Cardiac Output

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
