Diagnosing Paroxysmal Atrial Fibrillation: Are Biomarkers the Solution to This Elusive Arrhythmia?

Figure 1

An ECG recording from a continuous cardiac monitor from a patient suffering from paroxysmal atrial fibrillation (PAF) lasting for several hours. The arrow marks the onset of AF, characterised by a variable R-R interval (representing the time between two successive ventricular contractions) and loss of P-waves (absence of coordinated atrial activity) (unpublished).
