Typical symptoms of lithium intoxication are summarized in Table 2 [122-127]. The clinical picture of hthium intoxication is dominated by neuromuscular and cerebral symptoms in mild cases apathy, muscle weakness, tremor, and unsteady gait are seen. In more severe cases speech disturbances, myoclonic twitching, coma and convulsion can occur. Pulse irregularities and circulatory collapse may supervene. Lithium often causes T-wave flattening or inversion on the electrocardiogram, but clinically important cardiovascular effects are rare, with sinus-node dysfunction reported most often [123]. Residual neurological sequelae consisting of cerebellar dysfunction with ataxia, neuropathy and supra-bulbar symptoms are not unusual. 

Tacrine can cause mild hepatotoxicity, which is selfresolving on discontinuation. Other side effects, including those related to cholinergic effects, are nausea, emesis, diarrhea, abdominal pain, dyspepsia, rhinitis, myalgia, tremors, and excessive urination. Overdose symptoms include seizures, muscle weakness, low blood pressure, severe nausea, vomiting, fast and weak pulse, irregular breathing, and slow heartbeat. 

The measured TTS funetions also depend on the CFD threshold and CFD zero eross level used. One reason may be the normal degradation of the CFD timing performanee at low pulse amplitudes. Another reason is noise, whieh impairs prineipally the timing of small-amplitude pulses. Irregular pulses may also be eaused by photoeleetron emission from the first dynode or by elastieally scattered electrons at the first dynode. 

The technique just described requires the porous medium to be sealed in a cell, so It cannot be used with pellets of irregular shape or granular material. For such materials an alternative technique Introduced by Eberly [64] is attractive. In Eberly s method the porous pellets or granules are packed into a tube through which the carrier gas flows steadily. A sharp pulse of tracer gas is then injected at the entry to the tube, and Its transit time through the tube and spreading at the exit are observed. A "chromatographic" system of this sort is very attractive to the experimenter,... 

Count the number ot beats tor 30 seconds (it the pulse is regular) and multiply by 2. It the pulse is irregular, count the number ot beats for 60 seconds.

The nurse inspects the IV needle site every 30 minutes for signs of extravasation. Potassium is irritating to the tissues. If extravasation occurs, the nurse discontinues the IV immediately and notifies the primary health care provider. The acutely ill patient and the patient with severe hypokalemia will require monitoring of the blood pressure and pulse rate every 15 to 30 minutes during the time of the IV infusion. The nurse measures the intake and output every 8 hours. The infusion rate is slowed to keep the vein open, and the primary health care provider is notified if an irregular pulse is noted. 

Ventricular fibrillation is irregular, disorganized, chaotic electrical activity in the ventricles resulting in absence of ventricular depolarizations, and, consequently, lack of pulse, cardiac output, and blood pressure. 

AF is characterized as an extremely rapid (400 to 600 atrial beats/min) and disorganized atrial activation. There is a loss of atrial contraction (atrial kick), and supraventricular impulses penetrate the atrioventricular (AV) conduction system in variable degrees, resulting in irregular ventricular activation and irregularly irregular pulse (120 to 180 beats/min). 

Supraventricular tachycardias may cause a variety of clinical manifestations ranging from no symptoms to minor palpitations and/or irregular pulse to severe and even life-threatening symptoms. Patients may experience dizziness or acute syncopal episodes symptoms of HF anginal chest pain or, more often, a choking or pressure sensation during the tachycardia episode. 

Less sophisticated methods are often the initial tools for detecting qualitative and quantitative alterations of heartbeat. For example, direct auscultation can reveal the irregularly irregular pulse that is characteristic of AF. 

Physical signs may include hypotension tachycardia, bradycardia, irregular or no pulse cyanosis hypothermia and distant or absent heart and lung sounds. 

If the perturbations are in the form of spikes of an irregular nature, the problem is likely to be detector contamination. Such spikes are especially observed when dust particles have settled into the FID flame orifice. Of course, the problem may also be due to interference from electrical pulses from some other source nearby. Regular spikes can be due to condensation in the flow lines causing the carrier, or hydrogen (FID), to pulse, or they can be due to a bubble flow meter attached to the outlet of the TCD, as well as the electrical pulses referred to above. Baseline perturbations can also be caused by pulses in the carrier flow due to a faulty flow valve or pressure regulator. 

As is commonly known, what are called X-rays are produced when an electric discharge is passed through a high-vacuum tube. It has been shown that these rays are a series of irregular pulses in the ether, which are set up when the kathode particles strike the walls of the glass vacuum... 

Acute Nicotine is a very toxic drug in acute high doses (Taylor 1996). The lethal dose in adult humans is approximately 60 mg. Symptoms of acute poisoning include headache, dizziness, salivation, cold sweats, abdominal pain, nausea, vomiting, and diarrhea. Sensory disturbances, confusion, and convulsions also occur. Blood pressure drops, the pulse becomes weak and irregular, and respiration becomes difficult. Death usually results from respiratory failure.
