Figures

• 

  Figure 1.. The method to measure the P wave duration is to quantify the difference between the first (F) start of the P wave and the end (E) in the last one.[3] In this case, lead III is the lead that shows first the start of P wave and VF is the last one that records the end of P wave.

  Figure 2.. Rate of significant mitral regurgitation in the cardiac and clinical characterization of centenarians (4C) registry. This figure has been performed with data from Martínez-Sellés, et al.[1] AF: atrial fibrillation; IAB: interatrial block.

  Figure 3.. Prevalence of IAB in patients admitted with heart failure that are in sinus rhythm. This figure has been performed with data from Avarez García, et al.[21] IAB: interatrial block.
