Acute electrocardiographic changes after pneumonectomy
1Department of Medicine, Medical University of South Carolina, Charleston 29425, USA.
Postpneumonectomy electrocardiographic (ECG) changes are common and usually result from the surgery itself, not new heart problems. Recognizing these expected ECG findings can prevent misdiagnosis and unnecessary treatments.
Area of Science:
- Cardiology
- Thoracic Surgery
- Medical Diagnostics
Background:
- Electrocardiographic (ECG) changes following pneumonectomy are not well-established.
- Pneumonectomy is a major surgical procedure involving lung removal.
Purpose of the Study:
- To define the typical electrocardiographic (ECG) changes observed after pneumonectomy.
- To differentiate post-surgical ECG alterations from acute cardiac or pulmonary events.
Main Methods:
- Retrospective review of clinical data.
- Analysis of preoperative and postoperative ECGs from 15 pneumonectomy patients.
Main Results:
- All patients exhibited increased heart rate post-surgery.
- Common findings included transient atrial arrhythmias and ECG signs of acute cor pulmonale.
- Specific axis shifts (leftward QRS after left pneumonectomy, counterclockwise precordial transition after right pneumonectomy) were noted.
Conclusions:
- Postpneumonectomy ECG changes are generally attributable to the surgical procedure.
- Distinguishing these expected changes from acute cardiac events is crucial for accurate diagnosis.
- Correct interpretation can reduce patient morbidity and healthcare costs.

01:25Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...

An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
