Measurement of Blood Pressure

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Electrocardiogram

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...

Electrophysiology of Normal Cardiac Rhythm

Electrophysiology of Normal Cardiac Rhythm

The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...

Special considerations while measuring blood pressure

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Cardiac Action Potential

Cardiac Action Potential

Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
Ionic Basis of Cardiac Action Potentials

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Summary

Professional athletes with high-normal blood pressure show prolonged ventricular repolarization (TpTe interval) and increased TpTe/QT ratio, suggesting potential left ventricular remodeling. Further research is needed to understand clinical implications.

Background:

Disturbances in ventricular repolarization are linked to cardiac changes in athletes.
Limited data exists on repolarization in professional athletes with prehypertension compared to amateurs.

Purpose of the Study:

To compare ventricular repolarization measures between professional and amateur athletes with high-normal blood pressure.
To investigate potential cardiac remodeling in athletes with elevated blood pressure.

Main Methods:

Thirty professional and thirty amateur track and field athletes were divided into four groups based on sport level and blood pressure.
Ventricular repolarization parameters, including TpTe interval and TpTe/QT ratio, were measured.

Main Results:

Professional athletes with high-normal blood pressure exhibited a significantly prolonged TpTe interval (86 ± 10.94 ms) compared to other groups.
An increased TpTe/QT ratio was observed in professional athletes with high-normal blood pressure (p=0.001).
No significant difference in S-Tpc intervals was found between groups (p=0.605).

Conclusions:

Professional athletes with high-normal blood pressure demonstrate increased transmural dispersion of repolarization.
These findings suggest potential left ventricular remodeling in this athlete population.
Further studies are required to determine the clinical and prognostic value of these repolarization changes.
