Antiarrhythmics are drugs that are used to treat abnormal heart rhythms resulting from irregular electrical activity of the heart. There are many different types of antiarrhythmic drugs. Examples include: Amiodarone (Cordarone) Flecainide (Tambocor) Procainamide (Procanbid) Sotalol (Betapace) In addition, there are other types of heart drugs that can be used to treat arrhythmias, including: Beta-blockers such as metoprolol or Toprol XL, which reduce the heart's workload and heart rate. Calcium channel blockers such as verapamil or Calan, which also reduces the heart rate.

Sleepiness, tiredness and fatigue are complaints which must be thoroughly analyzed to eliminate blur and ambiguity.
Physiological sleepiness (โ€œsleep pressureโ€) increases while being awake and additionally underlies the circadian rhythm with a lower threshold to fall asleep during night time.
Excessive daytime sleepiness (EDS) is considered normal only after sleep deprivation. Clinically, EDS manifests by frequents daytime napping and/or reduced alertness with automatic behavior or - in its extreme form - in recurrent attacks of sudden, uncontrollable compulsion to sleep also in inappropriate situations (= โ€œsleep attacksโ€).
EDS is โ€œobjectivelyโ€ addressed by measuring the mean sleep latency to four to five nap opportunities throughout the day using the multiple sleep latency test (MSLT) or the maintenance of wakefulness test (MWT).
EDS denotes both, a ready entrance into sleep as well as difficulty in staying awake during daytime or accordingly in inappropriate situations. These two partially independent aspects of EDS are separately assessed by the โ€œpassiveโ€ MSLT and the โ€œactiveโ€ MWT respectively.
For that reason the MSLT and MWT only weakly correlate with each other when tested over a broad range of patients with EDS. It is important to keep in mind, that these tests are importantly influenced by a great variety of factors such as mood, anxiety, and motivation.
โ€œVigilanceโ€ comprises wakefulness, alertness and attention and therefore is more than just the reciprocal to sleepiness. Cognitive performance tasks such as Steer Clear Reaction Time Test (SCRTT) or driving simulators require the complete integrity of vigilance to achieve normal results. Hypersomnia is usually broadly defined as the combination of abnormally prolonged night-time sleep (regularly >10 h) with EDS during โ‰ฅ1 months.
On the other hand, the term hypersomnia has also been used in a narrower scene for the isolated abnormality of a prolonged night-time sleep need (>10 h). โ€œTirednessโ€, also in colloquial language often used for sleepiness, in a broader sense also describes the feeling of lack of energy, motivation and initiative.

These patients seek rest rather than sleep. They often cannot fall asleep when given the opportunity in spite of feeling tired, and hence, in an MSLT, do not show an abnormally short sleep latency. Furthermore, tiredness (and fatigue) as opposed to sleepiness has a mental (โ€œcentralโ€) and physiological (bodily or โ€œperipheralโ€) component, which the patients can readily distinguish. Patients with insomnia, mild sleep apnea syndrome, or depression rather suffer from mental tiredness than sleepiness during the day.
The simple subjective self-assessment using the Epworth Sleepiness Scale (ESS) quite reliably differentiates between sleepiness and mental tiredness (without sleepiness), which makes it a widely used test. The term โ€œfatigueโ€ is also heterogeneously used.
In physiology the โ€œfatigueโ€ implied a โ€œtime on task performance decrementโ€ to describe decreasing muscle force during a sustained physical effort. In clinical medicine one distinguishes physical (โ€œperipheralโ€) from mental (โ€œcentralโ€) fatigue and the term usually denotes a chronic and more abnormal situation than tiredness.
In a broad sense โ€œfatigueโ€ implies a deficiency in coping satisfactorily with mental and physical work load. The chronic fatigue syndrome entails both mental as well as a physical fatigue (so called โ€œleaden paralysisโ€ of limbs). Depressive states are often associated with insomnia and fatigue, but there are also cases with hypersomnia rather than insomnia ( non organic hypersomnia , โ€œatypical depressionโ€ or โ€œhypersomnolent depressionโ€)
Sometimes these patients have a tendency to spend much of the day lying in the bed without actually sleeping (so called clinophilia). The basic and clinical aspects of fatigu

Your body needs bile, but if it has too much cholesterol in it, that makes gallstones more likely. It can also happen if your gallbladder can't empty properly. Pigment stones are more common in people with certain medical conditions, such as cirrhosis (a liver disease) or blood diseases such as sickle cell anemia.
