N\u00ba1 of seven Little Etudes<\/a><\/strong> for beginner and intermediate piano players based on different cardiac electrophysiology aberrations for the first day of WHRW2020: World Heart Rhythm Week<\/a><\/strong> (1-7 June 2020). Etude N\u00ba1 is based on Atrial Fibrillation<\/a><\/strong> (AF), an irregular heart rhythm that increases the risk of catastrophic stroke<\/a>. The simplest way to detect AF is through a simple pulse check<\/a>, that can be confirmed by an ECG (electrocardiogram<\/a>).<\/p>\n\n\n\n

In ECG traces, AF is recognized by the absence of P waves and presence of fibrillatory waves, and irregular intervals between heartbeats. Here, musical trills represent the fibrillatory waves. The melody is taken from a Chopin nocturne (Op.62 No.1), which has many trills. The melody has been time-warped (in the notated score and in the performance) to match the irregular rhythms of an actual AF ECG.<\/p>\n\n\n\n
