Arrhythmia & Electrophysiology Review
|May 23, 2019
Summary
Managing monomorphic ventricular arrhythmias (MMVA) in athletes is crucial for preventing sudden cardiac death (SCD). Comprehensive evaluation and targeted therapies like radiofrequency catheter ablation can enable safe return to sports.
Area of Science:
- Cardiology
- Sports Medicine
- Electrophysiology
Background:
- Athletes with ventricular arrhythmias face risks of sudden cardiac death (SCD) during competition.
- Monomorphic ventricular arrhythmias (MMVA) can be benign or indicate underlying malignant substrates.
- Identifying conditions like hypertrophic cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy is vital.
Purpose of the Study:
- To review current recommendations for evaluating and managing athletes with MMVA.
- To guide physicians in risk stratification and return-to-sport decisions.
- To highlight effective therapeutic strategies for MMVA in athletes.
Main Methods:
- Comprehensive literature review focusing on MMVA in athletes.
- Analysis of diagnostic criteria for structural and electrical heart disease.
- Evaluation of treatment outcomes, including radiofrequency catheter ablation.
Main Results:
- MMVA requires thorough assessment to rule out serious cardiac conditions.
- Absence of structural heart disease often allows for effective treatment and return to play.
- Radiofrequency catheter ablation is a successful therapy for specific arrhythmias.
Conclusions:
- A systematic approach is necessary for managing athletes with MMVA.
- Timely diagnosis and intervention can mitigate SCD risk.
- Personalized management strategies are key for athlete safety and career longevity.

500
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...

01:16ECG Interpretation of Arrhythmias I: Sinus Arrhythmias
794
Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

01:28Mechanism of Cardiac Arrhythmias
1.7K
Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

The term self-esteem is often used generically, to refer to how people feel about themselves. However, according to research, there are three distinct constructs that should not be used interchangeably (Brown & Marshall, 2006).

01:52Regression Toward the Mean
6.9K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...
