“…The reported prevalence of ECG changes in patients with SAH ranges from 27% to 100% [3,[8][9][10][11][12]. Such wide variation may be due to differences in study design, investigators' definitions of ECG abnormalities, or the methods used to evaluate ECG changes.…”

“…Brouwers et al [9] found that during the first 72 h after SAH, ECG changes were the most pronounced. Di Pasquale et al [10] found that 90% of patients had ECG abnormalities within the first 48 h following SAH, suggesting that studies in which surveillance is started later in the course of illness may miss significant data [8].…”

“…Holter monitoring of patients in recent times has led to greater detection and reporting rates of arrhythmias in SAH patients. In the largest study to date in which Holter technology was used, Di Pasquale et al [10] first obtained a 12-lead ECG at the time of admission from a sample of 120 patients with SAH. Holter monitoring was started on the same day, and a total of 107 adequate Holter recordings were obtained.…”

Subarachnoid haemorrhage (SAH) is a neurological emergency with high mortality rates. It is mainly caused by rupture of an aneurysm (congenital/infectious/ traumatic) or rupture of an arteriovenous malformation. Electrocardiograms (ECGs) done in patients with SAH have shown morphological changes as well as arrhythmias. Subarachnoid haemorrhage (SAH) patients have often been misdiagnosed to have cardiac abnormalities based on their ECGs when in many of those instances the ECG change had been the result of the SAH itself. They have led to unnecessary and wasteful investigations and therapies in many occasions. Hence the current article is an effort at consolidating the information available in an attempt to avoid possible errors in diagnosis by house staff and internists. There are two mechanisms that might mediate ECG changes in patients with SAH, i.e. autonomic neural stimulation from the hypothalamus or elevated levels of circulating catecholamine. Hypothalamic stimulation may cause ECG changes without associated myocardial damage whereas elevated catecholamine levels have been correlated with QT-interval prolongation and myocardial damage.

The continuous shortage of organs necessitates the use of marginal organs from donors with various diseases, including arrhythmia-associated cardiac failure. One of the most frequently used anti-arrhythmic drugs is amiodarone (AM), which is given in particular in emergency situations. Apart from its anti-arrhythmic actions, AM provides anti-oxidative properties in cardiomyocytes. Thus, we were interested in whether AM donor pretreatment affects the organ quality and function of livers procured for preservation and transplantation. Donor rats were pretreated with AM (5 mg/kg of body weight) 10 minutes before flush-out of the liver with a cold (4°C) histidine-tryptophan-ketoglutarate solution (n ϭ 8). Livers were then stored for 24 hours at 4°C before ex situ reperfusion with a 37°C Krebs-Henseleit solution for 60 minutes in a nonrecirculating system. At the end of reperfusion, tissue samples were taken for histology and Western blot analysis. Animals with vehicle only (0.9% NaCl) served as ischemia/reperfusion controls (n ϭ 8). Additionally, livers of untreated animals (n ϭ 8) not subjected to 24 hours of cold ischemia served as sham controls. AM pretreatment effectively attenuated lipid peroxidation, stress protein expression, and apoptotic cell death. This was indicated by an AM-mediated reduction of malondialdehyde, heme oxygenase-1, and caspase-3 activation. However, AM treatment also induced mitochondrial damage and hepatocellular excretory dysfunction, as indicated by a significantly increased glutamate dehydrogenase concentration in the effluate and decreased bile production. In conclusion, AM donor pretreatment exerts anti-oxidative actions in liver preservation and reperfusion. However, these protective AM actions are counteracted by an induction of mitochondrial damage and hepatocellular dysfunction. Accordingly, AM pretreatment of donors for anti-arrhythmic therapy should be performed with caution. Liver Transpl 15:763-775, 2009.
