Bystander Effect02:09

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
Bullying02:04

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
Deindividuation00:57

Deindividuation

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.
Aggression01:47

Aggression

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for hire...
Attribution Theory00:56

Attribution Theory

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958). An internal factor is an...
Naturalistic Observations02:30

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Summary
This summary is machine-generated.

A patient experienced atrial flutter and wide complex tachycardia. Electrophysiology revealed an accessory pathway causing the tachycardia, which was successfully treated with ablation.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Cardiac Arrhythmias

Background:

  • Atrial flutter and wide complex tachycardia can present diagnostic challenges.
  • Understanding the mechanisms of supraventricular tachycardia is crucial for effective treatment.

Observation:

  • A patient presented with intermittent non-sustained wide complex tachycardia and 1:1 atrioventricular (AV) conduction alongside atrial flutter.
  • Electrophysiology testing identified a counterclockwise, isthmus-dependent right atrial flutter with AV nodal conduction.
  • An incidental left lateral accessory pathway was found, explaining the wide complex tachycardia episodes.

Findings:

  • Following successful bidirectional cavotricuspid isthmus block, a sustained wide complex tachycardia emerged.
  • This sustained tachycardia exhibited identical counterclockwise right atrial activation and rate, mimicking atrial flutter.
  • The mechanism was identified as antidromic atrioventricular re-entrant tachycardia (AVRT) with bystander right atrial activation.

Implications:

  • This case highlights the importance of considering accessory pathways in the differential diagnosis of wide complex tachycardia.
  • Successful ablation of the accessory pathway resolved the tachycardia, demonstrating the efficacy of this intervention.
  • Accurate electrophysiological mapping is essential for differentiating true atrial flutter from re-entrant tachycardia mimicking flutter.
