Insights

Patients with acromegaly experience significant electrical heart disturbances, including prolonged QT intervals and arrhythmias. Early cardiac monitoring by a cardiologist is recommended for these patients.

Area of Science:

  • Cardiology
  • Endocrinology

Background:

  • Hormonal imbalances, particularly in the thyroid, parathyroid, adrenal, and gonadal glands, are well-researched regarding circulatory effects.
  • The relationship between growth hormone and the cardiovascular system requires further investigation.

Purpose of the Study:

  • To describe cardiovascular complications in acromegaly detectable by standard electrocardiogram (ECG) and 24-hour Holter monitoring.

Main Methods:

  • Compared 28 acromegaly patients (15 with hypertension) with 20 hypertensive patients and 20 healthy controls.
  • All subjects underwent physical examination, resting ECG, and 24-hour Holter monitoring.
  • Evaluated heart rate, arrhythmias, QRS, QT, QTc intervals, and atrial/ventricular hypertrophy.

Main Results:

  • Acromegaly patients exhibited significant electrical cardiac disturbances.
  • Substantial QT and QTc interval prolongation and QRS complex prolongation were observed.
  • Supraventricular and ventricular arrhythmias were more frequent in acromegaly patients.

Conclusions:

  • Acromegaly is associated with significant, potentially life-threatening electrical heart function disturbances.
  • Acromegaly patients warrant early and regular cardiological monitoring.

Holter Monitor: 24-Hour Monitoring01:23

Holter Monitor: 24-Hour Monitoring

Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...
Pulse rhythm01:30

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...
Electrocardiogram01:29

Electrocardiogram

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and the T...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
