palpitation不是单指心跳加速

Heart palpitation symptoms can feel like:

• Skipped heartbeats
• Fluttering heartbeats
• Heartbeats that are too fast
• Heartbeats that are pumping harder than usual

You may feel heart palpitations in your throat or neck, as well as your chest. Heart palpitations can occur whether you're active or at rest, and whether you're standing, seated or lying down.
