In Section 2, we intro duce and analyze the Hofstadter Chaotic Heart sequence, which is constructed as a difference of the Q-sequence and the Conway sequence.
We call the sequence [(H(n)).sub.n[greater than or equal to]1] the Hofstadter Chaotic Heart sequence (A284019).
We shall now analyze the Hofstadter Chaotic Heart sequence using Pinn's statistical technique and the Maternal Spot Generation method (we also study the same analysis with Pinn's generational method that estimates whether the integer part of [2.sup.k-1/2] is the beginning point of the kth generation of Q-sequence for k [greater than or equal to] 12; results observed are mainly similar to the values of Table 2).
While we explore the Hofstadter Chaotic Heart sequence, we also introduce and study the Brother sequence, which offers meaningful experimental results and intriguing observations in terms of new inferences for Hofstadter's Q-recurrence.
Bradycardia (slow heart rates) occurred more frequently than ventricular tachycardia (abnormal and dangerous rapid or chaotic heart
rhythms): In the study, 19 of 50 patients had at least one bradycardia episode (with a rate of 26 bradycardia events per patient month); there were only two sustained ventricular arrhythmia episodes during the follow-up.
Most episodes are caused by a rapid and/or chaotic heart
beat or ventricular fibrillation (the uncoordinated contraction of the cardiac muscle of the ventricles of the heart).
Intensive Care Unit nurse Jacinta Gately said at around 12.45am, medics gathered by her bed noticed a chaotic heart
rhythm on a monitor and checked Savita's pulse.
The causes of the chaotic heart
rhythms associated with atrial fibrillation (AFib) appear to be sources in the heart that look like tiny, electrical spinning tops or "rotors," according to a study out of UCLA and two other institutions.
These devices can shock a heart out of ventricular fibrillation, a fast, chaotic heart
rate that leads to cardiac arrest.
Heart attacks can trigger a chaotic heart
rhythm called ventricular fibrillation and lead to sudden cardiac arrest.
Ventricular fibrillation, a condition of chaotic heart
activity, causes most SCA episodes.
Heart Attack Sudden Cardiac Arrest Cause: Reduced blood supply Cause: Chaotic heart
