ECG changes

Wellens’ syndrome is a clinical presentation with a particular pattern of electrocardiographic (ECG) T-wave changes associated with critical, proximal left anterior descending (LAD) coronary artery lesions.

Intracranial hemorrhage, including subarachnoid hemorrhage (SAH), is associated with many cardiac effects, including cardiac rhythm abnormalities, ischemic electrocardiographic (ECG) changes, elevated cardiac troponin levels, and regional wall motion abnormalities on echocardiogram.

A right bundle branch block (RBBB) is rarely found in patients with myocardial infarction (MI). In addition, back pain is an atypical complaint in patients with angina. It is a challenge for clinicians to recognize and carefully assess a patient’s complaints even if they are admitted for pain that is “atypical” of MI. When ECG shows changes, clinicians need to pay attention to a tricky, hidden, and life-threatening occlusion of the coronary artery.

The objective of this study was to investigate the metabolic and osmotic effects of different doses of glycerol or a glycerol – propylene glycol mixture in Sarda sheep with the aim to identify those able to beneficially modify ewe’s metabolic status without harmful changes in red blood cell (RBC) indices.

Cardiovascular comorbidity in COPD is common and contributes to increased mortality. A few population-based studies indicate that ischemic electrocardiogram (ECG)-changes are more prevalent in COPD, while others do not.

In this paper, a report is made on an application of the mentioned capability of wavelet transform for grasping subtle changes and discontinuities in electrocardiogram (ECG) signals. From the signal processing point of view, it shows that the diagnostic of ECG signals is carried out by excluding any recognised abnormality as singular points or irregular structures.

(BQ) The document divided into three sections, the first part presents the basic principles of ECG and normal and abnormal ECG patterns. The following chapters describe ECG changes in different heart diseases, emphasising efficiency and fluency in interpreting the patterns. The final section provides 150 ECG tracings for trainees to practise and interpret on their own.

Chief complaint: Reason for admission to the ICU. History of present illness: This section should included pertinent chronological events leading up to the hospitalization. It should include events during hospitalization and eventual admission to the ICU. Prior cardiac history: Angina (stable, unstable, changes in frequency), exacerbating factors (exertional, rest angina). History of myocardial infarction, heart failure, coronary artery bypass graft surgery, angioplasty. Previous exercise treadmill testing, ECHO, ejection fraction.

In order to address these issues, we have attempted to detail many of the key relevant advances in signal processing. Chapter 1 describes the physiological background and the specific autonomic mechanisms which regulate the beat-to-beat changes of timing and morphology in the ECG, together with the cause and effect of breakdowns in this mechanism. Chapter 2 presents an overview of the primary issues that should be taken into account when designing an ECG collection system.

Pulmonary Embolism (See also Chap. 256) Chest pain due to pulmonary embolism is believed to be due to distention of the pulmonary artery or infarction of a segment of the lung adjacent to the pleura. Massive pulmonary emboli may lead to substernal pain that is suggestive of acute myocardial infarction. More commonly, smaller emboli lead to focal pulmonary infarctions that cause pain that is lateral and pleuritic. Associated symptoms include dyspnea and, occasionally, hemoptysis. Tachycardia is usually present.
