“…in our case, the stage and location of the tumour suggested cardiac metastases, which may occur in up to 18% of cases of squamous cell lung cancer [22]. There are some case reports of patients with lung cancer after surgical treatment in whom myocardial metastases also mimicked aCS on the ECg [23,24]. There are three common ECg patterns that could indicate cancer infiltration of the myocardium: ST-segment elevation, negative T waves (as in our case), and right bundle branch block [22].…”

In cancer patients changes in the electrocardiogram (ECG) may indicate various causes. The presented case concerns a patient with advanced left lung cancer who presented deep inversion of T waves during ongoing chemotherapy. We excluded acute coronary syndrome, acute pulmonary embolism, and myocarditis. Subsequently, we suspected metastases to the myocardium; therefore, we performed cardiac magnetic resonance imaging, which however did not confirm that. The cardiac magnetic resonance imaging showed residual post-inflammatory changes in the left lung. We publish this case to show that the inflammatory process of lung segments adjacent to the heart may cause temporal myocardial oedema, resulting in ECG changes that may mimic acute coronary events.

Lung cancer subjects undergo fatigue because of chronic stress, which affects their autonomic nervous system activity. The appearance of pseudo-myocardial infarction and T-wave inversion with no clinical symptoms were also detected in lung cancer condition. The present work aims to identify any variation in electrocardiogram (ECG) of lung cancer subjects in comparison with that of healthy controls. The lead II ECG (band-pass filtered from 0.5 to 35 Hz and sampled at 200 Hz) was recorded for 5 minutes using MP45 (Biopac System Inc, Goleta, CA) from 110 consecutive lung cancer subjects and 30 healthy controls in supine position. Acknowledge 4.0 (Biopac System Inc) software was used to study the ECG parameters. ST-segment elevation of 0.2 and 1 mV and T-wave inversion was found in ECG of lung cancer subjects without any clinical history of cardiac disorder. Subjects 1 and 2 were observed with ST-segment elevation. Subject 3 exhibited biphasic T-waveform, and subjects 4 to 8 revealed T-wave inversion in ECG. The ECG of lung cancer subjects varies from healthy controls’ ECG. ST-segment elevation similar to myocardial infarction and T-wave inversion existed in a few subjects who had no cardiac anomaly. These unique changes in ECG suggested a high level of fatigue due to a higher amount of cholinergic and adrenergic neurotransmitters secreted, leading to increased sympathetic activity and decreased parasympathetic activity.
