Insights

Atrial fibrillation management in Asia requires balancing rate and rhythm control strategies. New catheter ablation techniques offer alternatives to medication for maintaining sinus rhythm.

Area of Science:

  • Cardiology
  • Electrophysiology

Background:

  • Atrial fibrillation (AF) is a growing epidemic in Asia.
  • Managing AF involves stroke risk, anticoagulation, and rate versus rhythm control.
  • Emerging catheter ablation techniques provide new rhythm control options.

Purpose of the Study:

  • To review current evidence on rate and rhythm control in atrial fibrillation.
  • To analyze treatment strategies for general AF patients.
  • To examine specific patient subgroups including obesity, heart failure, and thyroid disease.

Main Methods:

  • Literature review of current evidence.
  • Analysis of pharmacological and interventional treatment options.
  • Focus on clinical practice guidelines and recent studies.

Main Results:

  • Evidence supports both rate and rhythm control strategies depending on patient profile.
  • Catheter ablation is increasingly effective for rhythm control.
  • Subgroup analysis highlights tailored approaches for specific comorbidities.

Conclusions:

  • Optimal AF management requires individualized rate or rhythm control decisions.
  • Catheter ablation offers a valuable option for rhythm control in select AF patients.
  • Further research is needed for specific populations with AF.

Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

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...

Fibril-associated Collagen01:11

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

ECG Interpretation of Rhythms01:24

ECG Interpretation of Rhythms

An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....

Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...
