Law enforcement officers carry handcuffs on their utility belts‚ usually within a protective leather case (Hill). Here are some steps on how to properly arrest someone. First‚ you need to know how to properly approach the suspect. One thing

CARDIAC TUMORS INTRODUCTION Cardiac tumours occur quite rarely‚ with metastatic neoplasms three times more prevalent than primary tumours. A large variety of benign and malignant tumours of the heart have been described. These tumors are found mainly in the heart‚ but can occur in the pericardium or the great arteries. Secondary cardiac involvement from malignant tumors of adjacent organs (lung‚ thymus) or from kidney (Wilms tumor) or liver‚ or even remote organs‚ are also seen. ANATOMY AND PHYSIOLOGY

Further‚ the paper describes some segments of ECG waveform which can identify the segments and how ECG signal can be used to distinguish between different arrhythmias. Keywords—the ECG signals; waveform; cardiac activity; electrocardiogram; cardiac vector I. Introduction The heart is the most important organ in both human body and vertebrate animals. The

Cardiac Cycle The cardiac cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat. The cardiac cycle can be subdivided into two major phases‚ the systolic phase and the diastolic phase. Systole occurs when the ventricles of the heart contract. Accordingly‚ systole results in the highest pressures within the systemic and pulmonary circulatory systems. Diastole is the period between ventricular contractions when the right and left ventricles

Cardiac catheterization is often referred to as coronary angiography or a coronary angiogram. It is a radiographic procedure that is used to look at and visualize the heart and the coronary arteries. During a cardiac catheterization it is possible for the cardiologist performing the procedure to see how effectively blood is flowing through the coronary arteries. In addition‚ this procedure allows the cardiologists to see how blood is moving through the chambers of the heart and how effective the
Premium Atherosclerosis Myocardial infarction Cardiology
The cardiac electrical activity is produced and controlled by the Sinoatrial (SA) node in the right atrium and the Atrioventricular (AV) node in the interatrial septum. The electrical signals move through the cardiac conduction system fibres causing the atria and ventricles to contract and relax regularly between 60-100 bpm [1].when those electrical signals are interrupted as a result of a damage in the conduction system‚ the heart rate would become irregular or would either increase resulting in

This means that in 2002 there were 11‚446 arrests compared to 20‚330 arrests made in 2008. During this time the total population only grew by about 300‚000 citizens or about 1.5%. The increase of arrests was definitely due to policy change‚ as is illustrated when comparing population growth numbers by the increase in people actually
Premium Terry v. Ohio Crime Fourth Amendment to the United States Constitution
Fourth Amendment of the United States Constitution states: Prohibits unreasonable searches and seizures and sets out requirements for search warrants based on probable cause. This amendment impacts law enforcement because police need a warrant to make arrests and searches. This is not applicable if the officer has first-hand knowledge of an event and the evidence is likely to be destroyed or the subject will abscond if time is taken to get a warrant. If a warrantless search is made by the police that should

The major question has always been whether it is constitutional and justifiable for the SAP to use force‚ especially deadly force‚ in order to arrest a person seen as a criminal or prevent or control crime. This question is even more pressing in mainly that section 11 of the Constitution guarantying every single person in a state the right to life‚ this include even those who find themselves doing
