|September 1, 1977
Summary
This study introduces a novel graphic method to track changes in electrocardiograms (ECGs) for hypertension patients. This visual tool aids in assessing ventricular hypertrophy and treatment effectiveness over time.
Area of Science:
- Cardiology
- Medical Informatics
- Biomedical Engineering
Background:
- Serial changes in electrocardiograms (ECGs) are crucial for monitoring patients with hypertension.
- Assessing left ventricular hypertrophy and biventricular hypertrophy is key in managing hypertensive heart disease.
Observation:
- A graphic method was developed to visualize serial ECG changes using 14 measurements.
- A triangular grid plots posterior probabilities for normal, left ventricular hypertrophy, and biventricular hypertrophy categories.
Findings:
- The method allows plotting successive ECGs as points on a triangle, revealing patterns of change over time.
- These graphical patterns correlate with clinical information, validating the approach.
- The display is efficiently generated using computer graphics terminals.
Implications:
- This visual tool can aid clinicians in evaluating hypertensive patients' status regarding ventricular hypertrophy.
- It offers a method to assess the efficacy of antihypertension therapies.
- The graphic display provides a dynamic overview of cardiac status in hypertensive individuals.

01:30Pulse 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...

01:29Electrocardiogram
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.

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

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...
