Insights

The COVID-19 pandemic severely impacted interventional electrophysiology services, causing a drastic decline in procedures. Public health interventions helped suppress local transmission, allowing services to resume with strict precautions.

Area of Science:

  • Cardiology
  • Public Health

Background:

  • The COVID-19 pandemic presented unprecedented challenges to healthcare systems globally.
  • Interventional electrophysiology services are crucial for managing complex cardiac arrhythmias.

Purpose of the Study:

  • To assess the impact of the COVID-19 pandemic on interventional electrophysiology services in affected regions.
  • To understand the changes in working patterns and the health of staff and patients during the pandemic.

Main Methods:

  • A review of electrophysiology laboratory records from Wenzhou (China), Milan (Italy), and London (UK).
  • Inspection of catheter lab records and interviews with electrophysiologists.
  • Correlation of activity decline with national COVID-19 case numbers.

Main Results:

  • A significant decline in interventional electrophysiology activity was observed in all three cities, closely following the rise in COVID-19 cases.
  • Workflow dropped to less than 5% of normal during restrictions, limited to emergency procedures.
  • Electrophysiologists were redeployed to emergency roles in two of the three centers.

Conclusions:

  • Interventional electrophysiology services are highly vulnerable during pandemics and social difficulties.
  • Intense public health interventions are effective in controlling local disease transmission.
  • Stringent precautions enable the resumption of electrophysiology services post-pandemic, as demonstrated in Wenzhou.

Electrophysiology of Normal Cardiac Rhythm01:19

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...

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...

Cardiac Action Potential01:30

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.

Electrocardiogram Fundamentals

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
Parts of an ECG
An ECG utilizes electrodes on the skin...

Mechanism of Cardiac Arrhythmias01:28

Mechanism of Cardiac Arrhythmias

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.

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...
